Simple Summary: Drug repurposing offers a valuable approach for utilizing FDA-approved drugs to address new diseases, including cancer, while significantly reducing the time and cost associated with drug development. In this review, we highlight the anticancer potential of anthelmintic benzimidazole derivatives, such as mebendazole (MBZ), fenbendazole (FBZ), flubendazole (FLBZ), and albendazole (ABZ), with a particular focus on their efficacy against blood cancers. These compounds operate through multiple mechanisms, including disrupting microtubule formation, regulating the cell cycle, inducing cellular differentiation, and modulating key signaling pathways involved in cancer progression. The ability of benzimidazoles to exert these diverse effects on malignant cells suggests their promise as therapeutic agents for hematological cancers. Furthermore, investigating their use in combination with standard-of-care treatments may lead to the development of novel, more effective therapeutic strategies, offering new avenues of hope for patients with blood malignancies. Drug repurposing is a strategy to discover new therapeutic uses for existing drugs, which have well-established toxicity profiles and are often more affordable. This approach has gained significant attention in recent years due to the high costs and low success rates associated with traditional drug development. Drug repositioning offers a more time- and cost-effective path for identifying new treatments. Several FDA-approved non-chemotherapy drugs have been investigated for their anticancer potential. Among these, anthelmintic benzimidazoles (such as albendazole, mebendazole, and flubendazole) have garnered interest due to their effects on microtubules and oncogenic signaling pathways. Blood cancers, which frequently develop resistance and have high mortality rates, present a critical need for effective therapies. This review highlights the recent advances in repurposing benzimidazoles for blood malignancies. These compounds induce cell cycle arrest, differentiation, tubulin depolymerization, loss of heterozygosity, proteasomal degradation, and inhibit oncogenic signaling to exert their anticancer effects. We also discuss current limitations and strategies to overcome them, emphasizing the potential of combining benzimidazoles with standard therapies for improved treatment of hematological cancers.

In this study, we explore the synthesis of silver nanoparticles (AgNPs) using calyx wastes from Abelmoschus esculentus (okra) and evaluate their anthelmintic potential against poultry pathogen Raillietina spp. The ultraviolet‐visible (UV‐vis) spectrum of nanoparticles showed an absorbance peak at 425 nm, confirming AgNP formation. Fourier transform infrared spectrophotometry (FTIR) analysis indicated the presence of functional groups responsible for reducing silver ions, and X‐ray diffraction (XRD) patterns confirmed the crystallinity of the nanoparticles. Dynamic light scattering (DLS), scanning and transmission electron microscopy (SEM and TEM) analyses were used to measure the size (20–50 nm) and morphology (spherical) of the synthesized AgNPs. The dose‐dependent in vitro anthelmintic efficacy was highest at 125 μg/ml of AgNPs, resulting in paralysis and death within 0.54 and 1.29 hours, respectively, while untreated control parasites survived for ~72 hours. The SEM micrographs of the treated parasites showed swelling and blebbing of the tegument. Histochemical localization studies showed a remarkable decline of tegumental and neurotransmitter enzymes involved with the parasite's metabolism and regulation of the endogenous physiological processes. This study underscores the potential of okra calyces in the green synthesis of AgNPs and provides a novel approach to developing alternative anthelmintics that interfere with the host‐parasite interface.

Background: 1,3,4-thiadiazole nucleus is a flexible nucleus. There are numerous biological activities showed by this nucleus. Anticancer, anthelmintic, antimicrobial, anti-inflammatory, antioxidant; anti-HIV, anti- tubercular and anti-carbonic anhydrase are a few activities showed by 1,3,4-thiadiazole derivatives. This project study aimed to investigate the anthelmintic and in silico anticancer activity of derivatives of 1,3,4-thiadiazole. Materials and Methods: The UV visible spectrophotometer (Shimadzu UV-1900) has been used to determine λmax of the synthesized molecules. The FT-IR (Bruker Alpha-II) spectrometer was used for IR spectra (4000-400 cm-1) via the KBr disc method. Proton (1H) and Carbon-13 (13C) NMR spectra were recorded in CDCl3 or (D6) DMSO at 300-500 MHz and 101-125 MHz, respectively, using the Bruker AV-III 400 spectrometer (Germany). High-Resolution Mass Spectra (HRMS) were obtained using the Xevo G2-XS QT of Mass Spectrometer (USA) with positive ESI mode at 70 eV. Results: The bonding energy for compounds 1, 2 and 3 were all in the range -42.929 to -48.909 kcal/mol. Results of the docking study shows interactions of compound 3 with the neighboring residues and showing significant anticancer activity. The presence of o-nitro, m-nitro and p-hydroxy groups makes compounds 1 (105.77%), 2 (131.67%) and 3 (155.54%) more potent and nearly equal in terms of inhibition percentage when compared to standard ascorbic acid. Compound-1 [5-([1,1'-biphenyl]-4-yl)- N -(2-nitrobenzylidene)- 1,3,4-thiadiazol-2-amine] showed significant anthelmintic activity. Conclusion: The biological profiles of these new generations of thiadiazoles would represent a fruitful matrix for further development of better medicinal agents. [ABSTRACT FROM AUTHOR]

The roots of Cyperus compressus (Cyperaceae) have traditionally been used to treat intestinal helminthiasis in India. This study was designed to examine the abnormalities caused on Raillietina echinobothrida Megnin, 1880, and Syphacia obvelata, Rudolphi, 1802, on exposure to the root methanolic extract of C. compressus, using scanning electron microscopy. Worms were placed in extract concentration of 30mg/mL and on paralysis, worms were dehydrated in acetone grades and images were taken. The extract was then processed for GC-MS study to detect the compounds present in it. The images portrayed damaged microtriches in R. echinobothrida and loss of annulations and wrinkled cuticle were observed in S. obvelata. Compared to the damages caused by the reference drug, the results were milder. GC-MS study revealed 30 prominent peaks where 7-Methyl-Z-tetradecen- 1-ol acetate, was the most abundant compound which was detected at retention time 20.48 and with a relative abundance of 60.49. Its efficacy could be contributed to these detected compounds in the extract. [ABSTRACT FROM AUTHOR]

Background: Helminthiasis is a major concern in the livestock sector due to the immense afflictions in the production and economy of the farmer. Chemical anthelmintics are used to combat them and parasites are acquiring resistance against these drugs. Hence, the development of new drugs or alternatives is the need of the hour for combating such infestations. This study was undertaken to determine the effect of methanolic leaf extract of Tectona grandis on strongyles. Materials and Methods: The dried leaves of Tectona grandis were subjected to Soxhlet extraction using methanol, and the extract was tested for its anthelmintic activity in vitro using egg hatch assay and larval motility assay. A dose of 250, 125, 62.5, 31.25, 15.625, and 7.8125 mg/ mL was used for the study. Fresh strongyle ova were exposed to different concentrations of the extract and observed after 48 hours for the hatch. L3 larvae obtained from coproculture were subjected to treatment with extract at different concentrations, and mortality per unit time was calculated. Fourier transform infrared (FTIR) spectroscopic analysis and Gas chromatography-mass spectrometry (GC/MS) were performed to identify the chemical nature of the extract. Results: There was a dose-dependent inhibition of hatch and larval mortality with a maximum inhibition of hatch at 250 mg/mL. There was a cent percent hatch in control wells and no loss of progressive motility in the larval motility test. On exposure to the extract, the larvae progressively lost their motility, and finally, there were caesurae of movement which indicated their death. The extract at 250 mg/mL killed all the larvae by 30 min, whereas, at 31.25 mg/mL, the mortality was 66.6% after 2 hr. Conclusion: The results suggest that methanolic extract from Tectona grandis leaves has a promising anthelmintic property and further studies are required for the isolation of active molecules.

Haemonchus contortus is a hematophagous nematode with a high reproduction rate, considered to be the main problem in grazing small ruminants. Therefore, treatment alternatives based on the use of plant extracts are sought. This study aimed to evaluate the ovicidal activity of Artemisia cina against the parasite Haemonchus contortus and to chemically characterize the extract with the highest biological activity through gas chromatography coupled with mass spectrometry (GC-MS). The extracts to be evaluated were obtained through the maceration technique using methanol, ethyl acetate, and n-hexane. The extracts were taken to total dryness and challenged against H. contortus eggs using the egg-hatching inhibition technique described by the World Association for the Advancement of Veterinary Parasitology (WAAVP). The methanolic extract (ME) showed 100 % ovicidal activity at a concentration of 4.25 mg/ml, being the most active at a low concentration; therefore, it was characterized by GC-MS. ME mainly contains fatty acids and terpenes; among them are hexadecanoic acid and 2-[4-methyl-6-(2,6,6-trimethylcyclohex-1-enyl)hexa-1,3,5-trienyl][cyclohex]-1-en-carboxyaldehyde. The characterized compounds have shown previously reported anthelmintic activity so that ovicidal activity may be associated with them. In conclusion, the methanolic extract of A. cina had a higher ovicidal activity at low concentrations; this is probably due to the presence of fatty acids and terpenes. [ABSTRACT FROM AUTHOR]

Haemonchosis is an infection caused by the Haemonchus contortus worm, a blood-sucking gastrointestinal parasite that can also infect humans. Orthosiphon aristatus (Blume) Miq leaves have been shown to have anthelmintic activity due to the presence of saponins, flavonoids, and tannins. This study aimed to determine the anthelmintic activity of ethanol extract of Orthosiphon aristatus (Blume) Miq leaves against H. contortus. The infective H. contortus larvae were divided into six treatment groups: a 0.5% ethanol extract concentration group, a 1% ethanol extract concentration group, a 2% ethanol extract concentration group, a 4% ethanol extract concentration group, a positive control group (+), and a negative control group (-), each with four replicates. The study was conducted in six hours, with observations made at the 1st, 2nd, 4th, and 6th hours. The results showed that the death of the larvae increased with higher ethanol extract concentrations and longer exposure to the ethanol extract of Orthosiphon aristatus (Blume) Miq leaves. The time of death for infective H. contortus larvae given the ethanol extract of Orthosiphon aristatus (Blume) Miq leaves was at the 4th hour, and the effective dose of the ethanol extract as an anthelmintic was at the concentration of 0.5%.

The surveillance and treatment of parasites are important features of preventative healthcare plans in zoological institutes. The parasite control strategies employed in temperate regions often involve prophylactic anthelmintic treatments during seasons where the burden of gastrointestinal parasites in fecal testing is high. These strategies are, however, not applicable in the tropics, where temperatures remain high throughout the year, allowing continuous parasitic development. A risk-based parasite management strategy was adopted by a tropical zoological institute. For parasite surveillance, routine fecal direct smears and magnesium sulfate flotations were performed to determine parasitic prevalence. The frequency of fecal checks for the year was determined by the frequency at which clinically relevant parasitism (fecal tests that resulted in the animal being treated) was detected during routine fecal checks in the previous year. A yearly anthelmintic drug-class rotation schedule was also implemented. The total number of fecal tests performed per year and the number of animals with clinically significant parasitic disease decreased by 30.0% (637/2126) and 46.9% (207/451), respectively, over the four-year period of the study. Anthelmintic class rotation also improved the efficacy of fenbendazole in treating Strongyloides spp. infecting the group of orangutans. This parasite control strategy is a targeted approach to managing preventative healthcare, reducing the work required to perform routine surveillance tests whilst maintaining the health of the collection of animals.

Background and Aim: Schima wallichii Korth., commonly known as the needlewood tree (family Theaceae) has therapeutic uses in traditional Mizo medicine for human helminthiasis and serves as a balm against ectoparasites in animals. Although the medicinal properties have been studied experimentally, its use as a traditional anthelmintic remains unexplored. This study aimed to analyze the chemical components and antiparasitic activity of S. wallichii. Materials and Methods: The chemical analysis of S. wallichi bark extracts was conducted focusing on the secondary metabolites using petroleum ether, chloroform, and methanol. Gas chromatography-mass spectrometry (GC-MS) was used to identify the specific compounds. An anthelmintic susceptibility test was carried out against Raillietina tetragona, intestinal cestode parasite of fowl. Results: The methanol extract yielded the highest concentrations of alkaloids, carbohydrates, glycosides, sterols, saponins, and tannins among all the extracts. Sterols were the most abundant compounds in all extracts, with flavonoids being absent. Secondary metabolites were largely absent in the petroleum ether and chloroform extracts. The GC-MS data identified cholest-22-ene-21-ol as the major steroid component. The cestode parasite was inhibited in a concentration-dependent manner by the plant extract. The plant extract's anthelmintic activity was evident through observable damage to the parasite's outer structure. Conclusion: Phytosterols in S. wallichii bark are responsible for its anthelmintic properties. The mechanism and pharmaceutical properties of the anthelmintic molecule require further exploration.

Background and Aim: The continuous use of anthelmintic drugs has led to global issues of resistance. One breakthrough to address this problem is the utilization of bio-anthelmintics derived from active compounds in agro-industrial waste. This in vivo study investigated the effectiveness of Podang mango (Mangifera indica L.) fruit peel waste extract for anthelmintic purposes, using concentrations up to 5%. Materials and Methods: This study included 28 Etawa crossbred goats aged 17 months. Goats were randomly assigned to four groups: A negative control, an aqueous fruit peel extract (AFPE) group at 2.5%, another AFPE group at 5%, and a positive control receiving ivermectin. Goats chosen had egg per gram (EPG) counts surpassing 1000 before exposure to Haemonchus contortus. For 7 days within a 9-week study, AFPE from Podang mangoes was given. On the 7th day, the positive control group was administered ivermectin. AFPE dosage relied on the average abomasum fluid per kilogram of animal weight. The feeding regimen consisted of concentrate and Pennisetum purpureum cv. Mott is customized for the nutritional needs of livestock. Data on feed consumption, digestibility, average daily gain, percentage reduction in fecal egg count, body condition score, and clinical parameters were collected throughout the study. Results: At higher treatment levels (AFPE), there was a greater reduction in both EPG and fecal egg counts. The expected and normal ranges were maintained for consumption and digestibility. While body weight increased, FAMACHA parameters showed a decrease. Compared to the negative control group, substantial disparities (p < 0.05) existed for hemoglobin, red blood cells, and hematocrit in both the positive control and the treatment groups. Blood urea nitrogen and creatinine, indicative of liver and kidney health, were within normal ranges. Conclusion: At a concentration of up to 5%, Podang mango waste extract (AFPE) can function as a substitute for traditional helminth medicines or bio-anthelmintics in goats, enhancing their production.

Gastrointestinal parasitism is a major health and welfare problem in ruminants. Synthetic chemical anthelmintic drugs have led to the emergence of resistance in gastrointestinal strongyles, inducing the search for alternatives to control the infections that affect ruminants. The objective of this work was to evaluate the anthelmintic potential of plant extracts against Haemonchus contortus Rudolphi. Three plants of the Guadeloupean biodiversity, Momordica charantia L., Carica papaya L. and Sargassum spp., were selected based on their high polyphenolic content and natural abundance. The phytochemistry of plants was explored, a biological assay against the parasite H. contortus was carried out, and several hypotheses about the way of action were proposed by an innovative electrochemical screening method.

De novo drug design focused on in silico research of more effective and safe drugs is the essential stage of pharmacophore-based drug discovery. This study aimed to evaluate the anthelmintic potential of herbal ligand derivatives to suggest new drug scaffolds and examine fragment-based key-lock fit models of drug candidates to offer more potent drugs. The reversible inhibitors of the Carnitine Palmitoyltransferase 2 enzyme (CPT 2) have been evaluated as anthelmintic drug candidates because the increased CPT 2 substrate in the environment leads to the death of the nematode. Eriocitrin is a herbal molecule found in several plants, especially in the citrus peel. It has never been previously investigated for anthelmintic purposes, but it is a molecule found in some anthelmintic plants. Therefore, eriocitrin was determined as the scaffold of a novel anthelmintic drug candidate. To design new eriocitrin derivatives, positions 3 and 8 on the chromene ring of eriocitrin were chosen to insert five different side groups, such as hydrogen, propylsulfanyl, acetate, phenol, and aniline. Twenty-four derivatives designed with Biovia Discovery Studio 2020 Client were docked with the antinematodal drug target rat CPT 2 using AutoDock4.2 software. ADME properties and the binding mode of the most potent derivative were investigated. For the derivative with the best-scored molecule E05, the free binding energy was -9.08 kcal/mol, and the Ki value was calculated as 22.017 nM. E05, which had a better inhibition value than eriocitrin showed that the presence of phenol at the 3rd position in the chromene nucleus of eriocitrin facilitated CPT 2 inhibition. This research is the first study that shows the eriocitrin and E05 are potent anthelmintic molecules according to in silico docking tests. E05 is worth to be investigated comprehensively with further in vitro studies. [ABSTRACT FROM AUTHOR]

The resistance of the Haemonchus contortus, a parasite causing severe anemia in ruminants, to commercial anthelmintics emphasizes the need for alternative bio-anthelmintics. This study aimed to identify the molecular, chemical composition, and in vitro anthelmintic activity of Sargassum duplicatum against H. contortus. Molecular identification employed the Chelex method, with DNA diversity and phylogeny assessed using maximum likelihood in IQ-tree. The analyzed chemical composition included proximate, total flavonoid, and total phenols. Adult worm motility test (AWMT) and egg hatch inhibiting test (EHIT) were conducted at concentrations of 2, 4, and 6 mg/mL of S. duplicatum ethanolic extract. AWMT followed a completely randomized factorial design (5 replications, each with 5 worms), while EHIT used a completely randomized one-way design (5 replications, each with H. contortus egg batches from 3 adult female worms). The cox1 gene sequence revealed the Sargassum sample as S. duplicatum (KP101270.1) with 99.83% similarity. The results indicated that the identified concentrations of S. duplicatum ethanolic extract, and the observation time significantly influenced motility and egg hatchability (p<0.05). Both factors exhibited a significant interaction (p<0.05). Concentrations of 4-6 mg/mL reduced worm motility by up to 50% (LD50) within 6-8 hours, while concentrations of 2-6 mg/mL inhibited egg hatchability by more than 87% during 24 hours of incubation. In conclusion, S. duplicatum holds significant potential as a bioanthelmintic agent. [ABSTRACT FROM AUTHOR]

Anthelmintic medicinal plants can cause deformities in the external structure of parasites exposed to them. Sesbania sesban var. bicolor is a traditionally used anthelmintic medicinal plants used by the Santhal tribe of Assam. This study evaluates the damages caused by the methanolic extract on the tegument of Raillietina echinobothrida and Syphacia obvelata and also assesses its antioxidant activity. In addition, GC-MS study to identify the phytochemicals in the studied plant was also carried out. Worms were exposed to 30 mg/ml of the extract and the paralysed worms were processed for scanning electron microscopy study. Images obtained revealed extensive damage on the mouth, suckers, and cuticle/tegument of the worms. The study revealed that the plant possesses a good antioxidant activity. GC-MS of the plant revealed the presence of about 21 prominent peaks of which Octadecanoic acid, 2-hydroxy-1-(hydroxymethyl) ethyl ester was the most abundant. The activity of the plant may be attributed to the presence of these compounds which may be responsible for its antioxidant and anthelmintic activity. [ABSTRACT FROM AUTHOR]

Background: Helminth infection occurs due to contact with contaminated soils and poor hygiene practices. Even though there is immense progression in human medicine, infections that occur due to bacteria, fungi, viruses, and parasites persist as a crucial threat to public health. Over the years, many studies indicated cow urine has antimicrobial activity. Hence, this study looks into anthelminthic property of cow urine in Ascaris spp., and Trichuris spp., eggs. Methods: The soil sample was collected at the riverside, near the toilet area and at the pond area at an aborigine village in Malaysia. Next, floatation technique was used to isolate the helminth eggs and it was identified using a light microscope. The cow urine was prepared as raw cow urine (RCU), evaporated raw cow urine diluted with distilled water (ERCUD), evaporation raw cow urine diluted with saline (ERCUS) and evaporated filtered cow urine diluted with saline (EFCUS). Results: From the soil samples, mainly two types of helminths were found which were Ascaris lumbricoides and Trichuris trichiura. Evaporated cow urine diluted with saline showed the most prominent result in the destruction of helminth eggs. Conclusion: Evaporated cow urine possesses biochemical agents that can be used in the future as anthelmintic agents whereby further studies can be made to explore more possibilities to use cow urine as a potential anthelmintic agent.

Background Parasitic infections challenge vertebrate health worldwide, and off-target effects of antiparasitic treatments may be an additional obstacle to recovery. However, there have been few investigations of the effects of antiparasitics on the gut microbiome in the absence of parasites. Methods We investigated whether two common antiparasitics—albendazole (ALB) and metronidazole (MTZ)—significantly alter the gut microbiome of parasite-free mice. We treated mice with ALB or MTZ daily for 7 days and sampled the fecal microbiota immediately before and after treatment and again after a two-week recovery period. Results ALB did not immediately change the gut microbiota, while MTZ decreased microbial richness by 8.5% and significantly changed community structure during treatment. The structural changes caused by MTZ included depletion of the beneficial family Lachnospiraceae, and predictive metagenomic analysis revealed that these losses likely depressed microbiome metabolic function. Separately, we compared the fecal microbiotas of treatment groups after recovery, and there were minor differences in community structure between the ALB, MTZ, and sham-treated control groups. Conclusions These results suggest that a healthy microbiome is resilient after MTZ-induced depletions of beneficial gut microbes, and ALB may cause slight, latent shifts in the microbiota but does not deplete healthy gut microbiota diversity.

Helminths disease is one of the infectious diseases caused by the entry of parasites in the form of worm eggs into the human body through the human digestive tract due to pollution through the soil-transmitted helminth (STH). This study measured the in vitro effect of Areca catechu ethanol extract partitioning as anthelmintic against Ascaris lumbricoides worms using a 125 mg pyrantel pamoate control. The test animals used were living and mobile worms of A. lumbricoides, which were taken from the small intestines of pigs. The study group was divided into 5 groups, namely positive control (pyrantel pamoate) 125 mg), negative control (0.9% NaCl solution) and ethanol extract group A. catechu 10%, 20%, 30%. The results confirmed that the ethanol extract partition of A. catechu at exposure to a concentration of 30% showed a high level of efficacy in killing worms with an average time of death of A. lumbricoides worms at 6 to 12 hours compared to pyrantel pamoat solution. However, at exposure to concentration, 10% and 20% obtained a slightly longer average mortality time of 8 to 24 hours, respectively. Partitioning of A. catechu ethanol extract at a concentration of 30% showed the highest level of efficacy in killing A. lumbricoides worms based on average faster mortality time than the concentrations of 10% and 20% collected. Ethanol extract A. catechu has pharmacological therapeutic effects have various properties, including can be used for the treatment of diseases caused by parasites and also several other diseases.

The main objective of this research was to perform Gymnema sylvestre (Asclepiadaceae) extract's phytochemical screening and identify its therapeutic potential. Using a Soxhlet apparatus, the powdered plant material was extracted using ethyl acetate. The preliminary phytochemical analysis confirmed the presence of alkaloids, flavonoids, phenols, glycosides, and steroids. Gas chromatography–mass spectroscopy analysis of the extract was performed and confirmed the presence of 11 compounds. As per the quantitative analysis, the extract exhibited a phenolic content of 948 µg gallic acid equivalent/g dry weight, a total flavonoid content of 398 µg quercetin equivalent/g dry weight, and an alkaloid content of 487 µg atropine equivalent/g dry weight. As per the in vitro cytotoxicity test using A549 cells, the IC50 (half-maximal inhibitory concentration) value for the extract was found to be 76.06 ± 1.26 µg/mL, indicating its cytotoxic effect on the cells. The ethyl acetate extract showed significant antibacterial efficacy, as evidenced by a zone of clearance measuring 3 mm against Escherichia coli and 6 mm against Bacillus subtilis. For anthelmintic activity, the earthworm paralysis time induced by G. sylvestre extract (10 mg/mL) was 28.13 ± 0.8 min, and the time of death was 68.21 ± 1.72 min. In comparison, the reference drug, piperazine citrate (10 mg/mL), caused paralysis in 22.18 ± 1.02 min and resulted in death at 66.22 ± 2.35 min. Similarly, the coagulation time was notably prolonged, with blood clot formation observed at 1 min and 40 s, at a concentration of 1 mg/mL, which underscores the potential anticoagulant or hemostatic modulation properties of G. sylvestre extract. The test extract showed good inhibition of alpha-amylase activity and exhibited an IC50 value of 15.59 µg/mL. The IC50 value for DPPH (2,2-diphenyl-1-picrylhydrazyl)-scavenging activity for the extract was 19.19 µg/mL. Based on the GCMS results, the compound 2,7-dimethyl-undecane was selected for its anticancer potential. Docking studies were conducted with the epidermal growth factor receptor (EGFR) protein, specifically the 5WB7 variant associated with lung cancer. The docking score was −4.5, indicating a potential interaction. Key interaction residues such as ASN328, VAL350, and THR358 were identified. Overall, this research provides valuable insights into the phytochemical composition and diverse biological activities of G. sylvestre extract, offering a foundation for further exploration of its medicinal and pharmacological potential.

One of the most important factors limiting the growth and development of children is gastrointestinal helminths. A conscious anthelmintic herbal cure is a rational approach to establishing a sustainable public health program in the treatment of oxyurid infections that are mostly seen in children, disrupt development, frequently recur and are asymptomatic. This study aims to investigate the molecular mechanisms of the anthelmintic features of Artemisia annua L. and to compare the antinematodal effect of A. annua L. n-hexane extract with Albendazole (ABZ) in naturally infected mice. For this purpose, A. annua L. n-hexane extract was extracted and orally administered to Balb-c mice infected with Syphacia obvelata oxyurid species at 300, 600, and 1200 mg/kg doses for seven days. Mice were examined for changes in S. obvelata egg numbers on days -7, -1, 1, 3, 5, and 7 by the anal tape method. As a reference drug, ABZ was administered at a dose of 5 mg/kg for three days, and as solvent control, corn oil was given in the same way and time as the extract. Some components of A. annua L. were investigated for possible chemical interactions and free energy of binding in Haemonchus contortus β-tubulin (Hcβ-tubulin) protein and rat Carnitine Palmitoyltransferase II (RnCPT II) enzyme by in silico docking simulations. Stigmasterol and friedelin inhibit the RnCPT II enzyme in silico with 9.43 nM and 13.07 nM Ki values, respectively, while not binding to Hcβ-tubulin. Arteannuin-B and scopoletin inhibited both RnCPT II and Hcβ-tubulin. A. annua L. n-hexane extract at 1200 mg/kg dose reduced oxyurid eggs by 88% on the 7th day. ABZ caused a 65.58% reduction. As the result, arteannuin-B, scopoletin, stigmasterol and friedelin are worthy of isolation and investigation in vitro and in vivo in terms of their anthelmintic effect. They can be evaluated as potential anthelmintic molecules. [ABSTRACT FROM AUTHOR]

This study evaluated the ovicidal and larvicidal effects of a hydroalcoholic extract (HAE) and two fractions—one aqueous (Aq-F) and the other organic (EtOAc-F)—from dehydrated Cyrtocarpa procera leaves on Haemonchus contortus. In addition, the primary compounds in the HAE and the fractions were identified. The egg hatching inhibition (% EHI) and L3 larval mortality (% Mortality) tests were performed. The treatments used in the EHI test were HAE (12.5–200 mg mL-1), Aq-F (5 and 10 mg mL-1), and EtOAc-F (0.62–10 mg mL-1); for larval mortality, HAE (50– 200 mg mL-1), Aq-F (20–40 mg mL-1), and EtOAc-F (2.5–40 mg mL-1). Thiabendazole (0.1 mg mL-1) and ivermectin (5 mg mL-1) were used as positive controls, while methanol (3 %) and distilled water were negative controls. The results were analyzed using a completely randomized design and an ANOVA. The main compounds in the extract and fractions were identified using high-performance liquid chromatography. The HAE had a 100 % ovicidal effect at the highest concentration tested, while EtOAc-F had a nearly 100 % ovicidal effect at 1.25 mg mL-1, and Aq-F displayed the lowest ovicidal effect. Regarding larval mortality, the HAE exerted a larvicidal effect close to 80 % at 100 mg mL-1, while EtOAc-F displayed a larval mortality of 71.47 % at 20 mg mL-1. The chemical analysis indicated the presence of gallic acid, derivatives of gallic acid (gallates), kaempferol rutinoside, quercetin glycoside, and luteolin glycoside. This study shows evidence of the ovicidal and larvicidal properties of C. procera, which could make it useful as a natural anthelmintic in the control of H. contortus. [ABSTRACT FROM AUTHOR]

Praziquantel (PZQ) is a drug effective against several parasitic diseases of fish caused by Platyhelminthes. The study assesses the efficacy of selected in-feed PZQ doses in eliminating metacercariae Diplostomum pseudospathaceum in grass carp. The fish were infected with D. pseudospathaceum in laboratory conditions and subsequently treated with PZQ at daily doses of 30 (PZQ1), 50 (PZQ2), and 100 (PZQ3) mg/kg bw for seven days. The treatment trial was followed by a 23-day observation period during which the fish were parasitologically examined on days 0, 2, 8 and 23. Smaller fish were infected with a significantly higher (P < 0.05) number of metacercariae than bigger fish among three weight groups as follows: up to 7 g > 7 to 12 g > 12 g. The in-feed PZQ at doses of 30, 50 and 100 mg/kg bw for seven days was 47%, 84% and 88% effective against metacercariae D. pseudospathaceum, respectively. A significant decrease (P < 0.01) in moving and an increase (P < 0.01) in the immotile metacercariae in the eye's lens were recorded in all the trial groups on each sampling day. An increasing proportion of motile metacercariae in the post-treatment observation period was seen in PZQ2 and PZQ3, indicating a decreasing trend in the actual efficacy in an environment with no reinfection possibility.

Background: The present investigation was designed to investigate the protective effect of a natural product to control Anthelmintic in earthworm Eisenia fetida. We investigated the effectiveness of dried Artemisia monosperma leaves as an anthelmintic. Methods: Five groups (50, 100, 200 and mg/mL) of the AMLE extract were utilized in this study. Negative and positive controls consisted of distilled water and mebendazole (10 mg/ml). Five worms that were around the same size were placed to each Petri plate along with the test solution (20 mL) of the extract. Artemisia monosperma leaves methanolic extract was prepared and evaluated its ability in vitro as anthelmintic activity against earthworms (Eisenia fetida). The ABTS, FRPA and DPPH techniques were used to calculate the antioxidant activity. Also, the phytochemical investigation of methanolic extract was performed on GC-MS equipment. Result: Fourteen different biomolecules are predicted using GC-MS spectrum. Also, the AMLE had a greater percentage value of ABTS, FRPA and DPPH radical inhibition (94.5±0.03 trolox/gFW, 0.8±0.005 μmol/gFW and 92.6±0.3%) respectively. Moreover, IC50 of AMLE was obtained at 20.5±0.9 μg/mL for the A549 and 24.3±0.9 μg/mL for MCF-7 cell lines. In comparison to AMLE, Mebendazole (10 mg/mL) produced paralysis and earthworm death by 13.91±0.007 and 18.2±0.980 min, respectively, while, AMLE (200 mg/mL) showed 3.860±0.320 and 5.464±0.422 min, respectively. The treated worms’ surface architecture also had noticeable abnormalities, according to the histological study. The result of present study revealed that AMLE leaves can serve as a good natural source of potent antioxidants and anthelminthiasis medicines. Which promotes the conduct of numerous in vivo researches to discover an efficient treatment. [ABSTRACT FROM AUTHOR]

Background: Gastro-intestinal parasitism is an important worldwide animal ailment causing heavy production losses in grazing animals and it is more prevalent in developing countries like India, mainly due to warm temperature in association with poor management practices and inadequate control measures. It can affect production through weight loss, diarrhoea, anaemia, reduction in milk and wool production, reproduction changes and mortality in case of heavy infestations. The current study was planned to evaluate the in vivo anthelmintic activity of extracts of Carica papaya seeds in naturally-infested goats. Methods: Twenty-four helminth-infested goats of either sex were randomly divided into four treatment groups (T1 -T4 ); each having six goats and T1 served as untreated control while T2 received a single dose of albendazole @ 7.5 mg/kg body weight on day zero. Group T3 and T4 were respectively treated with aqueous and alcoholic extracts of Carica papaya seeds @ 100 mg/kg body weight orally daily for 30 days. Faecal egg count, haematological estimations and biochemical estimations were conducted on the zero, 10th, 20th and 30th day of the experiment. Result: Group T2, T3 and T4, showed a significant reduction in EPG count following treatment. All treated animals showed a significant increase in Hb, TEC, PCV and lymphocytes and a significant decrease in TLC, neutrophil and eosinophil levels on the 20th and 30th days of the experiment. The results indicated possession of good anthelmintic activity by both extracts with better results from the alcoholic extract of Carica papaya seeds. These herbal extracts can be a safe and therapeutically efficacious alternative to standard chemical drugs. [ABSTRACT FROM AUTHOR]

The aim of the present study was to evaluate the in vitro anthelmintic efficacy of aqueous and acetone extracts of pods of Acacia nilotica on the eggs and adult worms of Haemonchus contortus. Eggs and worms were exposed to five increasing concentrations of Acacia nilotica pod extracts (1.25; 2.5; 5.0; 10.0 and 20.0 mg/mL). The results showed dose-dependent ovicidal (p<0.001) and vermicide (p<0.05) activity against H. contortus. For the egg hatch inhibition assay (EHA), the rate of inhibition ranged from 31 to 70% for aqueous extract and from 41 to 81% for acetone extract, while Benzal (positive control) showed the highest inhibition rate of 91%. For adult nematode mortality test (AMT), no mortality was recorded between 0-h and 2-h in any of the treatment groups as well as the two controls. Mortalities were recorded from the 4th and 6th hour of incubation. Concentrations of 10 and 20 mg/mL recorded the highest mortality rate (>80%) after 4-h of incubation. These results suggest that A. nilotica pods can be used in the control of gastrointestinal nematodes. [ABSTRACT FROM AUTHOR]

Simple Summary: Aquaculture is vital for global food production, but parasites like Microcotyle sebastis pose challenges to Korean rockfish, leading to economic concerns. As there is a growing worry about drug resistance, we explored salinomycin, previously recognized for treating other parasites, to combat this issue. Our experiments revealed that salinomycin effectively lessens these parasites in Korean rockfish without significant side effects. Importantly, the treatment appeared potentially more stable when administered at a water temperature of 13 °C. This study suggests that salinomycin could be a promising alternative, especially if resistance against current treatments like praziquantel emerges. Aquaculture, a crucial sector of the global food industry, faces a myriad of issues due to parasitic invasions. One such parasite, Microcotyle sebastis, which afflicts Korean rockfish in South Korea, has a significant economic impact. The impending danger of resistance to traditional anthelmintics necessitates the exploration of new antiparasitic candidates. Although the efficacy of salinomycin against aquatic parasites such as ciliates and sporozoans is known, its influence on monogeneans has yet to be studied. Therefore, this study investigated the efficacy and safety of salinomycin for the treatment of M. sebastis infections, presenting the first exploration of salinomycin's therapeutic potential against monogeneans. In vitro examinations revealed a minimum effective concentration of salinomycin of 5 mg/kg, which led to necrosis of the haptor upon dislodging from the gill filaments. The one-time oral administration of the drug at concentrations of 5 mg/kg and 10 mg/kg showed a significant dose-dependent reduction in parasite counts, with no apparent behavioral side effects in Korean rockfish. Biochemical analyses monitored the liver, heart, and kidney enzymes, specifically aspartate transaminase (AST), alanine transaminase (ALT), blood urea nitrogen (BUN), and creatine kinase–myocardial band (CK-MB). At both 20 °C and 13 °C, no significant differences were observed in the levels of AST and ALT. However, at 20 °C, alterations in BUN levels were evident on Day 14, a deviation not observed at 13 °C. The CK-MB analysis revealed elevated enzyme levels at both temperatures when compared to the control group, reflecting the similar changes observed in terrestrial animals administered salinomycin. The biochemical data suggest that the oral administration of salinomycin is potentially more favorable at 13 °C than at 20 °C. Although our findings warrant further comprehensive studies, including on the long-term and potential effects on nontarget species and water quality, they also suggest that salinomycin could be considered as an alternative or adjunctive treatment if resistance to the currently used praziquantel against M. sebastis is confirmed.

Tapeworm infections cause insidious and irreversible effects in the infected individuals and some of them have already shown resistance to available drugs. A search for alternative treatment is urgently required. Phenolic compounds are amongst the most researched natural substances for their medicinal use. The present study aims to determine anthelmintic efficacy of two polyphenols Gallic acid and Catechin against the zoonotic rat tapeworm Hymenolepis diminuta. Both compounds are potent anti-oxidants and play major roles in combating pathogens, while their anthelmintic property according to our knowledge is yet to be explored. The parasite model H. diminuta was procured from intestine of infected rats raised in our laboratory. Two sets of parasites were treated in vitro with 5, 10, 20 and 40 mg/ml concentrations of each Gallic Acid and Catechin separately, another set of parasites were treated with standard dose of Praziquantel in RPMI 1640, while still another set of worms were kept in RPMI 1640 at 37 ± 10C with 1% Dimethyl sulfoxide as control. Motility and structural alterations were the parameters assessed for anthelmintic efficacy of the compounds. After paralysis the worms were processed for morphological, histological, and ultrastructural study and observed under light and electron microscope. Dose-dependent efficacy was observed in both compounds. Shrinkage of suckers, deformed proglottids and architectural alteration of the tegument were observed throughout the body of treated parasites compared to control. Although in terms of time taken for paralysis and mortality Gallic acid was more effective than Catechin, the degree of morphological aberrations caused were almost similar, except histological alteration was more in Catechin treated worms than in Gallic acid. Nevertheless, both Gallic acid and Catechin are suggested to possess anthelmintic efficacy besides other health benefits but extended studies are required to compare their efficacy.

Flagellaria indica (Family: Flagellariaceae) is a common climbing plant found primarily in tropical regions of many countries. The plant has various traditional uses, although most of them lack scientific published reports. The crude ethanolic extract of F. indica leaves was fractionated based on polarity using water, ethyl acetate, and n-hexane. Biological screening was conducted on the anthelmintic, blood coagulation, diuretic, and laxative activities of the water, ethyl acetate, and n-hexane fractions of F. indica leaves. In the anthelmintic test, the n-hexane fraction showed a moderate effect with paralysis times of 16.79 and 13.62 minutes and death times of 27.34 and 21.81 minutes, respectively, at doses of 25 and 50 mg/mL.In the blood coagulant test, only the water fraction showed a notable effect. The clotting times were 4.33, 6.02, 7.68, and 8.32 minutes, respectively, at doses of 200, 100, 50, and 25 mg/mL. Diuretic activity was performed to determine the increase in the volume of excreted urine, and electrolyte analysis of urine was performed to determine pH, density, conductance, and Na+, Cl-, K+ levels, as well as natriuretic, kaliuretic, saluretic, and CAI indexes. The ethyl acetate fraction showed better diuretic activity than the n-hexane fraction, while the water fraction did not reveal a notable diuretic effect. The Na+, Cl-, K+, natriuretic, and saluretic indexes were found satisfactory in the ethyl acetate fraction, and the CAI index was better in the n-hexane fraction. In the laxative test, the n-hexane fraction showed the best laxative properties, with an increase in stool weight of 38% and 54% at doses of 250 and 500 mg/kg, respectively. These results suggest that different fractions of F. indica leaves contain distinct phytochemicals that may be responsible for these biological effects. The isolation of bioactive compounds could help justify its traditional uses in modern medicine. [ABSTRACT FROM AUTHOR]

Objective: In the background of a very small number of effective anthelmintics available today with a narrow activity spectrum, and a rise in resistance against them among parasitic helminths, there is an urgent need for discovery of novel broad-spectrum anthelmintics displaying no or minimal toxicity towards the host. Silver being used since centuries for therapeutic purposes and considered safe for human consumption, we investigated anthelmintic activity of a colloidal nanosilver formulation Silversol®. Anthelmintic efficacy of the test formulation was assayed employing the nematode Caenorhabditis elegans as a model worm through a live-dead count. Results: Silversol® exerted anthelmintic action superior to one of the positive controls (Benzimidazole), and almost at par to another positive control (Ivermectin). At concentrations ≥ 2 ppm, it could kill all the worms present in the experimental well. Lower concentrations of silver were found to have a cuticle-damaging action on worms. Further investigation is warranted to assess whether Silversol® can exert similar potent activity against different species of parasitic helminths, and elucidate the underlying molecular mechanisms of action.

[Display omitted] • TRPM PZQ is characterized in Schistosoma mansoni using single channel electrophysiology. • TRPM PZQ is a voltage-independent, large conductance, non-selective cation channel. • TRPM PZQ activity can also be resolved using a membrane potential reporter dye. Ion channels have proved to be productive targets for anthelmintic chemotherapy. One example is the recent discovery of a parasitic flatworm ion channel targeted by praziquantel (PZQ), the main clinical therapy used for treatment of schistosomiasis. The ion channel activated by PZQ – a transient receptor potential ion channel of the melastatin subfamily, named TRPM PZQ – is a Ca2+-permeable ion channel expressed in all parasitic flatworms that are PZQ-sensitive. However, little is currently known about the electrophysiological properties of this target that mediates the deleterious action of PZQ on many trematodes and cestodes. Here, we provide a detailed biophysical characterization of the properties of Schistosoma mansoni TRPM PZQ channel (Sm.TRPM PZQ) in response to PZQ. Single channel electrophysiological analysis demonstrated that Sm.TRPM PZQ when activated by PZQ is a non-selective, large conductance, voltage-insensitive cation channel that displays distinct properties from human TRPM paralogs. Sm.TRPM PZQ is Ca2+-permeable but does not require Ca2+ for channel gating in response to PZQ. TRPM PZQ from Schistosoma japonicum (Sj.TRPM PZQ) and Schistosoma haematobium (Sh.TRPM PZQ) displayed similar characteristics. Profiling Sm.TRPM PZQ responsiveness to PZQ has established a biophysical signature for this channel that will aid future investigation of endogenous TRPM PZQ activity, as well as analyses of endogenous and exogenous regulators of this novel, druggable antiparasitic target.

[Display omitted] • The Schistosoma mansoni ion channel, TRPM PZQ , can be activated by membrane stretch. • Mechanical or ligand activation evokes similar single channel opening events. • TRPM PZQ is a polymodal ion channel gated by both chemical and mechanical stimuli. The parasitic flatworm ion channel, TRPM PZQ , is a non-selective cation channel that mediates Ca2+ entry and membrane depolarization when activated by the anthelmintic drug, praziquantel (PZQ). TRPM PZQ is conserved in all platyhelminth genomes scrutinized to date, with the sensitivity of TRPM PZQ in any particular flatworm correlating with the overall sensitivity of the worm to PZQ. Conservation of this channel suggests it plays a role in flatworm physiology, but the nature of the endogenous cues that activate this channel are currently unknown. Here, we demonstrate that TRPM PZQ is activated in a ligand-independent manner by membrane stretch, with the electrophysiological signature of channel opening events being identical whether evoked by negative pressure, or by PZQ. TRPM PZQ is therefore a multimodal ion channel gated by both physical and chemical cues. The mechanosensitivity of TRPM PZQ is one route for endogenous activation of this ion channel that holds relevance for schistosome physiology given the persistent pressures and mechanical cues experienced throughout the parasite life cycle.

Objectives: In this work, the photo components were investigated utilising GC-MS analysis and in vitro antioxidant activity, and the anthelmintic potential of methanolic extract of aerial parts of the Lagenaria siceraria (MEALS). By using the soxhlation method. Materials and Methods: MEALS were made from aerial components, and phytochemical analysis was carried out for a qualitative evaluation. The in vitro antioxidant activity was measured using the ABTS technique, and the current extract was utilised to analyse phytocomponents by GC-MS and study anthelmintic activity on Pheretima posthuma. The extract of Lagenaria siceraria included 59 components, according to the GC-MS study's phytochemical analysis. Results: Results from anthelmintic research reveal that MEALS had paralysis times between 4.76 and 2.17 min and death times between 6.18 and 2.34 min when compared to the medicine Albendazole, which is the gold standard (paralysis time 4.76 min to 2.17 min and death time 5.87 min to 1.96 min on Peritima posthuma in increasing order of concentration). The percentage of scavenging ranged from 33.31% to 82.33% (IC50 143) and by standard medicine (ascorbic acid) from 49.47% to 94.73% (IC50 103) using the ABTS technique in the evaluation of an antioxidant activity. Conclusion: Due to the presence of physiologically active phytocomponents, aerial sections of the Lagenaria siceraria (MEALS) were shown to be potent anthelmintic and antioxidant agents.

Illness bring about reduced cell creation of defensive mixtures prompting expanded harm to cell films; unavoidably, harm layers which lessens cell capacity to fix harmed tissue. Free extreme age has been embroiled in the aggravation of wound region 99 A medication which hinders lipid peroxidation is accepted to expand the reasonability of cells by working on the dissemination, forestalling cell harm, advancing DNA union, and so on and thus advancing the injury mending. Jc oil contains sugars, flavonoids, tannins, and triterpenoids, proteins a polysaccharides and unstable oil. Jc oil contains juniperin, which is tannins answerable for anthelmintic movement. Flavonoids have been reported to have intense cell reinforcement and free extremist rummaging impact, which is accepted to be one of most significant mixtures of wound mending. Subsequently, the upgraded wound mending might be free extremist searching activity of JC, and improved degree of cell reinforcement proteins in the granuloma tissues. Better collagenation seen affected by this JC might be a direct result of improved98. Anyway further investigations are expected to affirm the constituents liable for wound recuperating action. The medication has a critical anthelmintic movement which might be because of both impeding energy digestion and parallelizing the worm. This might be because of tannins. The oil of Juniperus communis linn. was fundamentally powerful in extraction, entry point and dead space wound models. This is additionally affirmed by histopathological studies. The oil has likewise strong hepatoprotective action. The injury recuperating and hepatoprotective movement might be because of presence of dynamic standards like tannins and flavonoids. Nonetheless, further investigations are expected to affirm the constituents answerable for the movement. To assess Juniperus communis linn (JC) oil for anthelmintic, injury recuperating and hepatoprotective exercises in rodents. [ABSTRACT FROM AUTHOR]

Plant tannins are known for their anthelmintic and antiparasitic activities and have been increasingly studied to battle the ever-growing problem of anthelmintic resistance. While tannins have been shown to exhibit these activities on their own, one approach would be to use them as complementary nutrients alongside commercial anthelmintics. So far, research on the interactions between tannins and anthelmintics is limited, and few studies have reported both synergistic and antagonistic effects depending on the type of tannin and the method used. These interactions could either strengthen or weaken the efficacy of commercial anthelmintics, especially if tannin-rich diets are combined with anthelmintics used as oral drenches. To study these interactions, a series of hydrolysable tannins (HTs) was selected, and their direct interactions with thiabendazole (TBZ) were evaluated by isothermal titration calorimetry (ITC), which allowed the detection of the exothermic interaction but also the roles and significances of different structural features of HTs in these interactions. Our results show that HTs can have a direct interaction with the benzimidazole anthelmintic TBZ and that the interaction is strengthened by increasing the number of free galloyl groups and the overall molecular flexibility of HTs.

Simple Summary: Parasitic infections are a significant problem in the sheep and goat industries worldwide. This issue is compounded by parasites becoming resistant to commercially available dewormers. Currently, the efficacy of tannins and other plant secondary compounds is being evaluated as natural dewormers in sheep and goats. The main objective of this study was to determine if cranberry vine was safe to feed pregnant and lactating ewes. The results of this study indicate that there were minimal effects on the growth and health of the ewe and her offspring from the consumption of a 50% cranberry vine pellet during late gestation and lactation. When creating any new anti-parasitic interventions, it is important to evaluate their effects across all life stages. This study had three objectives, which were to evaluate the effect of feeding cranberry vine pellet (CVP) on (1) ewes' body weights and BCS during late gestation and lactation; (2) ewes' milk quality during lactation; and (3) lambs' body weight and growth parameters from birth to 65 days of age. Across two years, 41 Dorset ewes were fed either a 50% CVP or a matching control pellet (CON) from 104 ± 1.60 days of gestation for 62.8 ± 0.68 days of lactation. Measurements were collected from ewes (BW, BCS, and milk) and lambs (BW and body size). Milk from CVP ewes exhibited reduced milk fat and solids (p < 0.01) and increased concentrations of milk urea nitrogen (p = 0.02) when evaluated for the treatment–time. There was no significant difference in the BCS, protein, lamb BW, or growth measurements for treatment–time (p ≥ 0.05). Additional research that targets blood biochemistry and metabolic assessments is needed to fully determine the impact of this pellet on ewes and lambs. [ABSTRACT FROM AUTHOR]

Simple Summary: Parasitic infections are a major problem in aquaculture, and there is a growing need for alternative treatments. This study investigated the efficacy of levamisole hydrochloride against Microcotyle sebastis infections in Korean rockfish. In vitro experiments showed that Microcotyle sebastis was sensitive to levamisole hydrochloride, and in vivo experiments tested different administration methods. In a controlled laboratory environment, oral administration has been demonstrated to exhibit efficacy without imposing any adverse effects on fish health. While these findings necessitate further investigation for practical application in actual aquaculture settings, they suggest the potential of levamisole hydrochloride as a therapeutic agent against Microcotyle sebastis infections in Korean rockfish. Consequently, this may contribute to the improvement of parasitic control strategies in aquaculture. Parasitic infections pose significant challenges in aquaculture, and the increasing resistance to conventional anthelmintics necessitates the exploration of alternative treatments. Levamisole hydrochloride (HCl) has demonstrated efficacy against monogenean infections in various fish species; however, research focused on Microcotyle sebastis infections in Korean rockfish (Sebastes schlegelii) remains limited. Therefore, this study aimed to evaluate the efficacy of levamisole HCl against M. sebastis infections in Korean rockfish with the goal of optimizing anthelmintic usage in aquaculture. In this study, we first assessed the susceptibility of M. sebastis to levamisole HCl in vitro. Subsequently, in vivo evaluations were conducted to assess the drug's efficacy, safety, and to identify optimal administration methods. In vitro experiments revealed concentration-dependent sensitivity of M. sebastis to levamisole HCl, with a minimum effective concentration (MEC) of 100 mg/L. In vivo experiments employed oral administration, intraperitoneal injection, and immersion treatments based on the MEC. Oral administration proved to be a safe method, yielding efficacy rates of 27.3% and 41.6% for 100 mg/kg and 200 mg/kg doses, respectively, in contrast to the immersion and injection methods, which induced symptoms of abnormal swimming, vomiting, and death. Biochemical analyses conducted to assess the safety of levamisole HCl revealed a transient, statistically significant elevation in the levels of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) on day three post-administration at 20 °C. Following this, no substantial differences were observed. However, at 13 °C, the enzyme levels remained relatively consistent, emphasizing the role of water temperature conditions in influencing the action of levamisole HCl. Our research findings substantiate the efficacy of levamisole HCl against M. sebastis in Korean rockfish, underscoring its potential for safe oral administration. These results provide valuable insights for developing parasite control strategies involving levamisole HCl in Korean rockfish populations while minimizing adverse impacts on fish health and the environment. However, this study bears limitations due to its controlled setting and narrow focus. Future research should expand on these findings by testing levamisole HCl in diverse environments, exploring different administration protocols, and examining wider temperature ranges.

Several countries have shown an increased prevalence of drug resistance in animal production due to the indiscriminate use of antibiotics and antiparasitics in human and veterinary medicine. This article aims to review existing methods using naturally occurring essential oils (EOs) and their isolated compounds (EOCs) as alternatives to antimicrobials and antiparasitic compounds in animal production and, consequently, to avoid resistance. The most-reported mechanism of action of EOs and EOCs was cell membrane damage, which leads to the leakage of cytoplasmic content, increased membrane permeability, inhibition of metabolic and genetic pathways, morphologic changes, antibiofilm effects, and damage to the genetic material of infections. In parasites, anticoccidial effects, reduced motility, growth inhibition, and morphologic changes have been reported. Although these compounds regularly show a similar effect to those promoted by traditional drugs, the elucidation of their mechanisms of action is still scarce. The use of EOs and EOCs can also positively influence crucial parameters in animal production, such as body weight gain, feed conversion rate, and cholesterol reduction, which also positively impact meat quality. The application of EOs and EOCs is enhanced by their association with other natural compounds or even by the association with synthetic chemicals, which has been found to cause synergism in their antimicrobial effect. By reducing the effective therapeutical/prophylactic dose, the chances of off-flavors – the most common issue in EO and EOC application – is greatly mitigated. However, there is very little work on the combination of EOs and EOCs in large in vivo studies. In addition, research must apply the correct methodology to properly understand the observed effects; for example, the use of only high concentrations may mask potential results obtained at lower dosages. Such corrections will also allow the elucidation of finer mechanisms and promote better biotechnologic use of EOs and EOCs. This manuscript presents several information gaps to be filled before the use of EOs and EOCs are fully applicable in animal production. [ABSTRACT FROM AUTHOR]

Background and Aim: Fasciolosis due to Fasciola gigantica is endemic to tropical countries and Fasciola hepatica in temperate climates, highly detrimental to livestock and known as foodborne zoonotic diseases. The strategic control of the disease is mainly the use of chemical anthelmintic. This study aimed to evaluate the anthelmintic properties of Artemisia vulgaris extract on the ova and adult stages of F. gigantica. Materials and Methods: Samples were collected from the Ampel Abbatoir, Boyolali District, Central Java, Indonesia. The ova from 20-gallbladders of cattle which were naturally infected with F. gigantica and 270 living F. gigantica worms were used in this study. The ovicidal assay was performed by incubating the ova with A. vulgaris in different concentrations, that is, 5%, 2.5%, and 1.25% for 5, 9, 11, 14, and 16 days. The efficacies were evaluated by quantification of ova degeneration during developmental stages in different time points and egg-hatch assay. The flukicidal effects were observed by mortality assay in 5, 10, 20, 40, 80, 160, 320, and 640 min incubations followed by scanning electron microscopy for surface morphology and histology of the fluke's transversal sections. Results: The concentration of 5% A. vulgaris showed the strongest ovicidal activities. The percentage of hatching ova on day 16 at concentrations of 5%, 2.5%, and 1.25% were 3.33%, 6.67%, and 16.67%. These ova hatch assay showed a significant reduction (p < 0.001) compared to untreated control. The flukicidal effect was significant (p < 0.001) at a concentration of 20%, with a mortality rate reaching 66.67% in the 40 min of incubation time. The surface properties of the adult worms, including the spine, tegument, acetabulum, intestine, and vitelline follicles, were disintegrated. Conclusion: The results showed that A. vulgaris has the potential ovicidal and flukicidal properties to F. gigantica. The active compounds remained necessary to be elucidated further and its modes of action would be interesting to be predicted by molecular docking modeling. [ABSTRACT FROM AUTHOR]

The pharmacokinetics and bioavailability of fenbendazole and levamisole were determined in Caspian turtles after a single intravenous (i.v.) and subcutaneous (s.c.) administration. Thirty turtles diagnosed as naturally infected with Serpinema microcephalus and Falcaustra armenica nematodes received fenbendazole (50 mg/kg) or levamisole (10 mg/kg) by i.v. and s.c. administrations. Blood samples were collected at time 0, 0.125, 0.25, 0.5, 1, 2, 4, 8, 12, 24, and 48 h after drug administration. Plasma drug concentrations were determined by a validated high‐performance liquid chromatography method. Data were analyzed by noncompartmental methods. The mean elimination half‐life of levamisole was 5.16 h and 12.03 h for i.v. and s.c. routes, respectively, and for fenbendazole, the mean elimination half‐life was 25.38 h (i.v.) and 29.77 h (s.c.). The total clearance and volume of distribution at steady‐state for levamisole and fenbendazole following i.v. administration were 0.22, 0.44 ml/g/h, and 1.06 and 7.35 ml/g, respectively. For the s.c. route, the peak plasma concentration of levamisole and fenbendazole was 10.53 and 5.24 μg/mL, respectively. The s.c. bioavailability of levamisole and fenbendazole was complete. Considering high anthelmintic efficacy and bioavailability after s.c. administration of levamisole and fenbendazole, and the absence of adverse effects, this route of administration is an easy and efficacious way of treating nematodes in Caspian turtles.

Oxyclozanide is a salicylanilide derivative anthelmintic drug with a well-known effect on parasites that cause infections in humans and animals. In this study, the effect of oxyclozanide on DNA damage in hemocytes of Galleria mellonella (L.) (Lepidoptera: Pyralidae) larvae, which has been used as a model organism in many fields, was investigated. Hemolymph was collected from the last instar larvae (7th instar) reared on artificial diets containing oxyclozanide at different concentrations (0.003%, 0.03%, 0.3%, and 1.5%) under laboratory conditions and then hemocytes suspension was prepared. Genotoxic damage in hemocytes was determined by the comet assay which enables microscopically detecting DNA damage and is a very sensitive assay in chemical genotoxicity. When compared to the control group, tail length, tail DNA percent, and tail moment values were significantly increased parallel with increasing oxyclozanide concentrations. While the tail length was determined as 5.11 ± 0.46 μm in the control group, it was significantly increased in all tested groups to 13.17 ± 0.53, 27.98 ± 1.08, 98.44 ± 0.77, and 137.67 ± 0.74 μm, respectively. Similarly to tail length, tail DNA percentage and tail moment levels were also significantly increased from 12.86 ± 0.74 to 91.96 ± 0.31 at the highest concentration of oxyclozanide. These results showed that oxyclozanide caused DNA damage in the hemocytes of G. mellonella. It is also known that hemocytes are an important bioindicator in determining the genotoxicity of anthelmintics to be used as insecticides within environmentally friendly limits. It is thought that our results will contribute to the studies in this field. [ABSTRACT FROM AUTHOR]

The designed compounds were synthesized and characterized by physicochemical and spectrophotometric (FTIR, Mass, 1H NMR, and elemental analysis) data. Among the compounds, compounds (Ic) and (Ig) have exhibited excellent anthelmintic activity with a good docking score and acceptable root-mean-square deviation (RMSD). [ABSTRACT FROM AUTHOR]

Pinworm ova were discovered on lesser hedgehog tenrec (Echinops telfairi) fecal exams. Ova were passthrough pseudoparasite pinworms originating from feeder roaches (Blaptica dubia). Roaches were maintained as a feeder colony and offered to tenrecs as a portion of their diet. Pinworms were identified as Leidynema appendiculata. This study aimed to determine if these pinworms could be eliminated from the roaches. Roaches were randomly assigned into groups (n = 24), including a control (A) and four treatment groups (B–E). Treatment group roaches received oral dosing of anthelmintic pyrantel pamoate at four concentrations (mg/g as offered): 3.5 (Group B), 14.0 (Group C), 26.0 (Group D), and 35.0 (Group E). Roach diets were made weekly and offered to roaches 2 consecutive days per week for 3 consecutive weeks. The total pinworm ova per gram of roach feces examined were visually reduced in all treatment groups compared to controls at the end of the feed dosing period (Day 23). Post-treatment pinworm numbers were visually reduced in all treatment groups compared to controls on Day 29 and Day 65. Groups receiving higher concentrations of the oral dosing (C–E) significantly differed from controls at Day 29 (p = 0.0086, p = 0.0045, and p = 0.0013, respectively) with a concentration-dependent response. Parasites were not eliminated in any group at Day 29 or 65 post-treatment, with an increasing visual trend indicating recontamination. This is the first report confirming a passthrough pseudoparasite in tenrecs from dubia roaches, and anthelmintic dosage research is warranted. [ABSTRACT FROM AUTHOR]

Piper sarmentosum Roxb. (Piperaceae) is a traditional medicinal plant in South-East Asian countries. The chemical investigation of leaves from this species resulted in the isolation of three previously not described compounds, namely 4″-(3-hydroxy-3-methylglutaroyl)-2″-β-D-glucopyranosyl vitexin (1), kadukoside (2), and 6-O-trans-p-coumaroyl-D-glucono-1,4-lactone (3), together with 31 known compounds. Of these known compounds, 21 compounds were isolated for the first time from P. sarmentosum. The structures were established by 1D and 2D NMR techniques and HR-ESI-MS analyses. The compounds were evaluated for their anthelmintic (Caenorhabditis elegans), antifungal (Botrytis cinerea, Septoria tritici and Phytophthora infestans), antibacterial (Aliivibrio fischeri) and cytotoxic (PC-3 and HT-29 human cancer cells lines) activities. Methyl-3-(4-methoxyphenyl)propionate (8), isoasarone (12), and trans-asarone (15) demonstrated anthelmintic activity with IC50 values between 0.9 and 2.04 mM. Kadukoside (2) was most active against S. tritici with IC50 at 5.0 µM and also induced 94% inhibition of P. infestans growth at 125 µM. Trans-asarone (15), piperolactam A (23), and dehydroformouregine (24) displayed a dose-dependent effect against B. cinerea from 1.5 to 125 µM up to more than 80% inhibition. Paprazine (19), cepharadione A (21) and piperolactam A (23) inhibited bacterial growth by more than 85% at 100 µM. Only mild cytotoxic effects were observed. [ABSTRACT FROM AUTHOR]

Cattle play an important role in the food chain as a major milk and meat producer. Helminths affect the health and production of livestock which need to be controlled efficiently and economically. The high usage of anthelmintic drugs has increased anthelmintic resistance to all available classes resulting in failed treatment options and economic losses. Herbs, which may be better options for animal and food safety, are among the best candidates to control these parasites. For this purpose, a research experiment was conducted. Twelve Sahiwal heifers were used for the evaluation of the anthelmintic activity of herbal dewormers composed of various parts of local herbs. Animals were divided into 4 groups A, B, C and D, all the groups, except group D were given herbal dewormer powder. In an experiment of 30 days, doses were given on a weekly basis. Fecal samples for egg counts, blood and serum samples were obtained fortnightly and subjected to statistical analysis. Results revealed that the animals receiving herbal dewormer @ 1400 mg/Kg had the best results and egg counts and hematological values were significantly (P<0.05) better than the control animals. The results of the study suggested that the herbal dewormer was efficient in reducing the worm counts as well as beneficial for the hematological profile of the cattle. [ABSTRACT FROM AUTHOR]

Gastrointestinal parasitosis constitutes important health problems, worsening over the years, due to inadequate use of drugs for its control, causing anthelmintic resistance. The objective of the present study was to evaluate the potential of Azadirachta indica (AZA) and Moringa oleifera (MOR) extracts in inhibiting egg hatching and in vitro migration of Haemonchus contortus larvae. A completely randomized experimental design was carried out, where 15 treatments and a dimethyl sulfoxide negative control were evaluated: MOR- 75, MOR-50, MOR-25, MOR-12.5, and MOR-6.25 mg/mL; AZA-75, AZA-50, AZA-25, AZA-12.5, and AZA-6.25 mg/mL; and thiabendazole (TBZ) TBZ-200, TBZ-100, TBZ-40, TBZ-20, TBZ-10 μg/mL. The extracts did not inhibit egg hatching capacity; however, we observed a complete decrease in motility in L1 larvae. The extracts affected larval migration (P < 0.0020) compared with controls (dimethyl sulfoxide and TBZ), with migration rate inhibition above 65 %. Probit analysis showed that the median effective concentrations were 60.41 and 65.69 mg/mL for M. oleifera and A. indica, respectively. The in vitro results suggest that the water extract of both plants has an anthelmintic action against gastrointestinal nematode larvae. [ABSTRACT FROM AUTHOR]

The present study aimed to evaluate the in vitro potential of aromatic plants Aloysia triphylla (cidró ou erva-luísa), Corymbia citriodora (eucalipto-limão), Lippia alba (falsa-melissa) e Piper gaudichaudianum (pariparoba), in helminths eggs and larvae, determine their main constituents. For this, the essential oils (OEs) of the plants were extracted from leafs, in the clevenger apparatus and to determine the main constituents was carried out the gas chromatography coupled to mass spectrometry. The Egg eclodibility assay (EEA) and Larval development test (DLT) were performed using essential oils at concentrations ranged from 75 at 0.2%. mg.mL, and all tests followed by commercial anthelmintic positive control and negative control distilled water. For EEA, A. triphylla e L. alba OEs demonstred equivalente efficacy to the commercial drug at all concentrations that was tested, while P. gaudichaudianum OE demonstred equivalente efficacy at 15 mg/mL and the C. citriodora OE at 10 mg/mL. About DLT, all concentratios of the studied essential oils were effective as the comercial drug results in this test. The dominant constituent in OEs were: geraniale (A. triphylla), citronellal (L. alba), linalool (L. alba) and a-humuleno (P. gaudichaudianum). Based on the results presented here, the OEs present potential for use as natural anthelmintics for the treatment of endoparasitosis in sheep. [ABSTRACT FROM AUTHOR]

Azadirachta indica (Neem) is an important medicinal plant containing diverse antimicrobial and antiparasitic activities. In the current scenario of emerging drug resistance, there is need of plant derived compounds having antiparasitic activity to counter infectious problem including helminths. Present research was conducted to evaluate the phytochemical composition, ovicidal and adulticidal activity of methanolic and ethyl acetate extracts of Azadirachta indica (Neem). The leaves of Neem were used for preparation of extracts and their composition was determined through high performance liquid chromatography (HPLC). Results showed that the methanolic extract had higher quercetin compounds than the ethyl acetate extract. The effect of these extracts on egg hatch and larval motility were tested in in vitro experiment. The results indicated that these were found effective to reduce the hatchability of eggs. Hatching percentage was 1.12% ± 1.01 in case of methanolic extract and 3.57% ± 0.97 in case of ethyl acetate extract. Ethyl acetate extract of A. indica killed all the worms at the concentration of 25 mg/mL at 6 hrs post exposure while methanolic extract showed 100 percent mortality at 10 hrs post exposure of same dose. Results were in dose-dependent manner. Ethyl acetate extract killed adult worms faster and at lower dose than methanolic extract. However, the methanolic extract of Neem had higher effectiveness than the ethyl acetate extract in preventing hatching of eggs. This research concludes that extraction solvent greatly affects the phytochemical composition and anthelmintic activities of Neem and this is effective to control the helminths.

Helminths, with an estimated 1.5 billion annual global infections, are one of the major health challenges worldwide. The current strategy of the World Health Organization to prevent helminth infection includes increasing hygienic awareness, providing better sanitation and preventative anthelmintic drug therapy in vulnerable populations. Nowadays, anthelmintic drugs are used heavily in livestock, both in case of infection and as a preventative measure. However, this has led to the development of resistance against several of the most common drugs, such as levamisole, ivermectin and thiabendazole. As many as 70% of the livestock in developed countries now has helminths that are drug resistant, and multiple resistance is common. Because of this, novel anthelmintics are urgently needed to help combat large-scale production losses. Prior to this review, no comprehensive review of the anthelmintic effects of essential oils and their components existed. Multiple review articles have been published on the uses of a single plant and its extracts that only briefly touch upon their anthelmintic activity. This review aims to provide a detailed overview of essential oils and their components as anthelmintic treatment against a wider variety of helminths. [ABSTRACT FROM AUTHOR]

Background: Gastrointestinal nematode (GIN) control is traditionally achieved with the use of anthelmintic drugs, however due to regulations in organic farming and the rise in anthelmintic resistance, alternatives are sought after. A promising alternative is the use of bioactive plant feeding due to the presence of plant secondary metabolites (PSMs) such as proanthocyanidins (PAs). This study focussed on the perennial shrub heather (Ericaceae family), a plant rich in PAs, highly abundant across Europe and with previously demonstrated anthelmintic potential. Methods: In vitro assays were used to investigate heather's anthelmintic efficacy against egg hatching and larval motility. Heather samples were collected from five European countries across two seasons, and extracts were tested against two GIN species: Teladorsagia circumcincta and Trichostrongylus colubriformis. Polyphenol group-specific ultraperformance liquid chromatography-tandem mass spectrometry analysis was performed to identify relevant polyphenol subgroups present, including the PA concentration and size and ratio of the subunits. Partial least squares analysis was performed to associate efficacy with variation in PSM composition. Results: Heather extracts reduced egg hatching of both GIN species in a dose-dependent manner by up to 100%, while three extracts at the highest concentration (10 mg/ml) reduced larval motility to levels that were not significantly different from dead larvae controls. PAs, particularly the procyanidin type, and flavonol derivatives were associated with anthelmintic activity, and the particular subgroup of polyphenols associated with the efficacy was dependent on the GIN species and life stage. Conclusions: Our results provide in vitro evidence that heather, a widely available plant often managed as a weed in grazing systems, has anthelmintic properties attributed to various groups of PSMs and could contribute to sustainable GIN control in ruminant production systems across Europe.
