Recent studies on the pathophysiology of COVID-19 are indicating that the Angiotensin convertase enzyme 2 (ACE-2) and transmembrane serine protease 2 (TMPRSS2) can act as a major component in the fusion of SARS-Cov-2 with target cells. It has also been observed that the expression of ACE-2 and TMPRSS2 can be altered in malignancies. Shedding light on this matter could be crucial since the COVID-19 pandemic interfered with many gastrointestinal cancer screening programs. Herein we discuss the possibility of severe forms of COVID-19 in patients with gastrointestinal cancers due to the gastrointestinal entry route of SARS-CoV-2 into the human body. The disruption of cancer screening programs caused by the current COVID-19 pandemic could therefore have massive negative health impact on patients affected by gastrointestinal malignancies.

The present study aimed at evaluating the presence of tick-borne apicomplexan parasites including Theileria ovis, Theileria lestoquardi, Theileria annulata, and Theileria orientalis in 92 cattle and 105 sheep from 6 different districts of Guilan and Mazandaran Provinces, in the southern littoral of Caspian Sea. Furthermore, ixodid ticks were collected from the same animals. Stained blood smears were microscopically evaluated for the presence of blood parasites, and a specific PCR was applied for the detection of Theileria species. Besides, ticks were subsequently examined by species-specific PCR. Microscopic examination of blood smears demonstrated no evidence of intraerythrocytic piroplasms. Species-specific diagnostic PCRs demonstrated that 52.17% of sheep blood samples were positive for T. ovis. In addition, 31.03% and 24.13% of cattle blood samples were positive for T. annulata and T. orientalis, respectively. Moreover, 3 species of the ixodid ticks, namely, Rhipicephalus annulatus (58.47%), Ixodes ricinus (29.82%), and Haemaphysalis inermis (11.69%), were identified in Guilan Province, while Hyalomma detritum (73.03%) and Rhipicephalus sanguineus (26.92%) were found in Mazandaran Province. Additionally, by obtaining the data with respect to tick-borne apicomplexan parasites in 122 infected ticks, 35.24%, 22.95%, and 2.45% of tick samples were positive for T. annulata, T. orientalis, and T. ovis, respectively. Species-specific PCR revealed that H. inermis and R. annulatus were positive for T. orientalis. In addition, T. annulata was found in R. annulatus, H. inermis, and H. detritum. Besides, T. ovis was the only species of Theileria found in R. sanguineus. In conclusion, the results revealed that T. annulata infection was prevalent among cattle and ovine theileriosis caused by T. ovis was the only Theileria species found in sheep in the studied areas of the southern littoral of Caspian Sea. R. annulatus, H. inermis, and H. detritum were the main vectors for T. annulata, followed by H. inermis and R. annulatus for T. orientalis, and R. sanguineus for T. ovis.

Herein, we provide the ecological niches of gastrointestinal nematode infections in Guilan, Mazandaran, and Golestan provinces. For this purpose, 2688 fecal specimens of sheep and cattle were subjected to the flotation method. For modeling procedure, the results were analyzed by considering 23 bioclimatic and environmental variables as well as 96 points/locations. Maximum entropy (model MaxEnt) was used to visualize the spatial distribution of gastrointestinal nematodes. The relative importance of all variables was also assessed by using jackknife analysis. The highest proportion of sheep infection with strongyle-type egg was observed in Golestan province (57.8%) and the lowest in Guilan province (49.5%), and eggs per gram (EPG) was around 21–29. The parasites with the highest proportion of infection in both domestic animals included strongyle-type eggs. Among the different bioclimatic and environmental variables, the biggest contributor to habitat suitability of the gastrointestinal nematode presence was found to be minimum temperature of the coldest month (Bio6), precipitation of driest quarter (Bio17), precipitation of coldest quarter (Bio19), and altitude. The MaxEnt model was able to provide a suitable guidance for predicting the probability distribution of gastrointestinal nematodes under bioclimatic and environmental variables, and the findings pave way for integrated gastrointestinal nematode surveillance and control strategies in the southern strip of Caspian Sea. In addition, the low intensity of gastrointestinal nematodiasis in ruminants may be associated with the frequent administration of anthelmintic drugs, where actions are needed to investigate drug resistance in the areas concerned and to provide anthelmintic drugs administration in a targeted manner.

Echinococcosis is considered a cosmopolitan zoonosis caused by different species of small taeniid tapeworms of the genus Echinococcus and is regarded as a neglected zoonosis. Cystic and alveolar echinococcoses are endemic diseases of Tibetan, Pamir, and Iranian plateaus. All of the countries within the Iranian plateau are affected by echinococcosis. Pakistan, Turkey, and Iran are the three most populous countries of the region, in which echinococcosis is highly endemic. The three neighboring countries share strong cultural and socioeconomic ties. The present study aimed to provide a broad review of the status of cystic and alveolar echinococcosis, summarizing the current knowledge about geographical distribution, molecular epidemiology, and transmission dynamics of Echinococcus granulosus sensu lato and Echinococcus multilocularis in this region. Additionally, we aimed to understand disease burden and risk factors as basic requirements for establishing a surveillance system and planning prevention and control programs. A considerable body of information is available on different aspects of echinococcosis in this region; however, several information and research gaps need to be filled before planning control programs. None of the countries in the region have an elaborate echinococcosis control program. Effective control programs require multi/intersectoral coordination within a One Health approach with a long-term political and administrative commitment and enhanced international collaboration among the three countries.

Cavitary lung formation with spontaneous pneumothorax has been rarely reported as a complication of COVID-19 pneumonia. We report a rare case of a 38 years-old male patient affected by COVID-19 pneumonia, exceptionally complicated by a simultaneous giant cavity in the right upper lung and a small right pneumothorax in the right hemithorax. Whilst pneumothorax emphysema, giant bullae and pneumothorax with alveolar rupture are known to potentially develop in COVID-19 patients as a result of high-flow O2 support, the exact origin of the giant lung cavitation in our patient could be not confirmed. Cavitary lesions – featured by high mortality rate - are reportedly associated with lung infarctions and can be the aftermaths of pulmonary embolism, a rather common sequela of COVID-19 pneumonia. Radiological imaging is critical to support clinical decision making in the management of COVID-19 pneumonia, since not only it can visualize and stage the disease, but it can also detect and monitor the eventual onset of complications over time, even following patient discharge from hospital.

Introduction: Diabetes is the most common endocrine disease that annually causes four million deaths in the world. It is not just a disease, however a series of metabolic disorders caused by defects in insulin secretion, insulin action, or both. Considering the importance of diet in the incidence and complications of diabetes, this study aimed to investigate the relationship between the dietary acid load with diabetes, which has recently been considered. Methods: This meta-analysis was first performed as a systematic review by searching in Google Scholar, Science Direct, PubMed, Wiley, Directory of Open Access Journals (DOAJ), Springer, Cochrane, ProQuest, and Scopus, as well as domestic databases including Magiran, SID, Irandoc, and Google Scholar. A total of 1511 articles were found that after reviewing and excluding irrelevant articles, five were included in the study. Results: In the present study, a significantly high heterogeneity was observed (I2 = 61.5, P = 0.01). A random effect model was used and the studies were weighted using the inverse-variance method. The odds ratio (OR) obtained from the meta-analysis was 1.17 (1.12-1.22). Examination of publication bias showed that the studies were symmetrically distributed in the funnel plot. Egger’s and Begg’s tests were also performed that showed no evidence for the existence of publication bias [Egger’s test (P ≥ 0.79) and Begg’s test (P ≥ 0.69)]. Conclusion: The results of the present meta-analysis showed a significant relationship between dietary acid load and the incidence of diabetes. This result is similar to most studies on the subject, except for one study, which was limited to the elderly male population. The number of studies in the present meta-analysis was low due to the limited number of research in this field.

Background: The Coronavirus disease 2019 (COVID-19) outbreak quickly has spread and became a pandemic. However, no approved therapeutics or effective treatment is available for the treatment of these patients. The present study was done to retrospectively assess the treatment strategies (e.g., pharmaceutical care services) for COVID-19 patients in selected hospitals and highlight the importance of such services in the management of a pandemic. Materials and Methods: Data from a series of COVID-19 patients (978 patients; 658 males [66.9%] and 324 females [33.1%]) admitted to the selected hospitals in Tehran from 20 February to 19 March 2020 were retrieved retrospectively from the Health Information System (HIS) of the hospitals. The statistical tests were used for analyzing the effect and correlation of the variables (drugs) with the average length of stay (ALOS) in the hospital. Results: Diverse medication classes and old drugs with or without strong evidence of therapeutic effects against the novel coronavirus, some previously tried as a treatment for SARS-CoV and MERS-CoV, were mostly used for the treatment of patients in the hospitals. Many medications (broad-spectrum antibiotics and antivirals) or combination therapies are used without evidence of their therapeutic effects during pandemics. Conclusion: Therefore, guidelines should be provided for the off-label use of these drugs by policymakers and stakeholders during a pandemic emergency due to high demands. Also, monitoring of the HIS data can play an important role in improving public health response to emerging diseases.

Cutaneous leishmaniosis (CL) is mainly caused by Leishmania major (rural-type) and Leishmania tropica (urban-type). CL is a major health problem in many regions of the world, and it is associated with health complications and economic loss. The identification and differentiation of Leishmania species are critical because the prevention and control methods, as well as management and therapeutic strategies, are different for each type of CL. The present study aimed to identify the parasite species responsible for CL in the study area using ITS1 and HSP70- based PCR-RFLP methods. A total of 147 stained slides were prepared from samples collected from CL patients, and these slides were positive for amastigotes of Leishmania species on microscopic examination. Forty-three Giemsastained slides with 2+ to 4+ grades were selected for molecular studies for the identification of the Leishmania species. DNA was extracted from the selected slides for the molecular studies. The amplification of HSP70 and ITS1 genes was performed by the PCR method. The PCR products were digested with the HaeIII restriction enzyme, and banding patterns of all samples were compared with reference strains. Overall, patterns of all the samples were found to correspond to the reference strains of L. major based on RFLP-PCR targeting HSP70 and ITS1 genes of the parasite, demonstrating the dominance of L. major as the causative agent of zoonotic cutaneous leishmaniosis (zCL) in the study area. This area is endemic for zoonotic CL, and further studies are required to determine the reservoir and natural infection of sand flies in this county.

Highlights • COVID-19 activates RAAS which induces oxidative stress leading to cytokine storm. • Ozone therapy can reduce oxidative stress. • Ozone therapy might be an excellent option as a complementary treatment for COVID-19., Severe forms of COVID-19 can evolve into pneumonia, featured by acute respiratory failure due to acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). In viral diseases, the replication of viruses is seemingly stimulated by an imbalance between pro-oxidant and antioxidant activity as well as by the deprivation of antioxidant mechanisms. In COVID-19 pneumonia, oxidative stress also appears to be highly detrimental to lung tissues. Although, inhaling ozone (O3) gas has been shown to be toxic to the lungs, recent evidence suggests that its administration via appropriate routes and at small doses can paradoxically induce an adaptive reaction capable of decreasing the endogenous oxidative stress. Ozone therapy is recommended to counter the disruptive effects of severe COVID-19 on lung tissues, especially if administered in early stages of the disease, thereby preventing the progression to ARDS.

Background There is no identified pharmacological therapy for COVID-19 patients, where potential therapeutic strategies are underway to determine effective therapy under such unprecedented pandemic. Therefore, combination therapies may have the potential of alleviating the patient’s outcome. This study aimed at comparing the efficacy of two different combination regimens in improving outcomes of patients infected by novel coronavirus (COVID-19). Methods This is a single centered, retrospective, observational study of 60 laboratory-confirmed COVID-19 positive inpatients (≥18 years old) at two wards of the Baqiyatallah Hospital, Tehran, Iran. Patient’s data including clinical and laboratory parameters were recorded. According to the drug regimen, the patients were divided into two groups; group I who received regimen I consisting azithromycin, prednisolone, naproxen, and lopinavir/ritonavir and group II who received regimen II including meropenem, levofloxacin, vancomycin, hydroxychloroquine, and oseltamivir. Results The oxygen saturation (SpO2) and temperature were positively changed in patients receiving regimen I compared to regimen II (P = 0.013 and P = 0.012, respectively). The serum level of C-reactive protein (CRP) changed positively in group I (P

Cystic echinococcosis (CE) is distributed worldwide, extending from China to the Middle East and from Mediterranean countries to the sub-Saharan Africa and South America. According to WHO, one million people around the world are suffering from CE with an estimated burden of 183,573 DALYs. The annual monetary burden of the disease due to treatment costs and CE-related livestock losses has been estimated at US$ 3 billion. CE is endemic in all countries within the WHO Eastern Mediterranean Regional Office (EMRO). The region, which includes most of the Middle East and North Africa, is one of the most ancient foci of the domestic cycle of CE and is recognized as one of the major hotspots of CE. There are 22 countries in the EMRO, where about 688 million people are living at risk of CE. In many EMRO countries, little is known about CE epidemiology and transmission. WHO included echinococcosis in a list of 17 neglected tropical diseases (NTDs) and 12 neglected zoonotic diseases (NZDs). Accordingly, different regional offices of WHO organized several initiatives for CE control and prevention. WHO's Western Pacific regional office considered echinococcosis as one of the region's major health topics, and several preventive measures have been implemented in the American region with the support of Pan American Health Organization (PAHO) in Argentina, Peru, Uruguay, and Chile. Although CE is endemic in all 22 EMRO countries, surprisingly, CE is absent from the health topics list of diseases and conditions in this region. Therefore, CE clearly requires further attention in the WHO EMRO agenda, and the need for elaboration of specific measures for CE control is becoming apparent in EMRO countries, where substantial collaborations among the member states and WHO EMRO is of paramount importance. Major topics of collaborative activities include training programs and health communication on different aspects of CE control, analysis of CE burden, national and international surveillance and disease registry systems, technical support to promote epidemiological studies for collecting baseline data, cost-benefit analysis of control interventions, and intersectoral cooperation among the agriculture, veterinary, medical, and health sectors.

Cystic Echinococcosis (CE) is a common neglected disease in many communities around the world, causing substantial costs on the endemic communities. CE has been considered a disease of adulthood, mostly affecting age groups within 20-59 years. However, CE can be seen in early life even in patients younger than 5 years. While the disease is frequently reported from children in the endemic areas across the globe, children CE is even more neglected and under-represented in the literature. Here we present an overview on this topic, summarizing main features of pediatric CE, current findings, existing knowledge and information gaps and research needs on this issue. In adults the lungs are involved in less than 30% of CE cases, however in children, pulmonary hydatid disease has been reported to be up to 67%. Different patterns of hydatid cyst and multiple organ involvement have been frequently observed in children, probably due to the immature filtering mechanisms of the liver and lungs during infancy and childhood and the role of intestinal lymphatic channels in dissemination of the parasite. It is believed that children immune system is less responsive to hydatid cysts, therefore serological assays of CE in children are likely to result in more false negative outcomes. As the proportion of internal organs occupied by the cyst is much greater in children than the adult patients, CE in children is more likely to be symptomatic than adults. Another peculiar aspect of pediatric CE is that the disease has been more frequently observed in boys than girls. According to the data recently published by the European Register of Cystic Echinococcosis the contribution of male patients is more than the females in children and adolescents. While males constitute 65% of the CE patients in 0-9 years age group, the proportion decreased to 50% and 45% in 30-39 and 70-79 years age groups, respectively. Considerable gaps of knowledge exist in pediatric echinococcosis and further investigations are required on this topic. Major information gaps in children CE include the lack of age-specific data, natural history, detailed clinical picture, clinical trials of non-surgical approaches, genotype data, specific guidelines for diagnosis and treatment and WHO ultrasound classification.

A standardized test for the serodiagnosis of cystic echinococcosis (CE) remains an important challenge because of the problems in specificity and sensitivity of the available commercial kits and lack of proper evaluation of antigen. Using appropriate sources of antigenic material is crucial in improvement of the serological methods such as enzyme-linked immunosorbent assay (ELISA). This study was conducted to evaluate the performance of protein named Echinococcus protoscolex calcium binding protein EPC1 for the detection of antibodies in sera from patients with CE. Expressed and purified recombinant protein EPC1 (rEPC1) was used as antigen in ELISA method. Characterization of the rEPC1 antigen was evaluated using the serum of 25 patients with both surgical and imaging confirmed CE and 25 healthy donors as negative controls. Also, a panel of sera including chronic toxoplasmosis (IgG positive), strongyloidosis, fascioliasis, toxocariasis, and kala azar were used and patients with related parasites were confirmed by medical laboratories or clinically by research centers using microscopy or specific ELISA. rEPC1 showed relatively promising performance in total IgG ELISA for the detection of antibodies in sera from the negative controls, and the cut off value 0.4 units of optical density at 490 nm was calculated for ELISA. In this study, sensitivity of 100%, specificity of 93.7, positive predictive value of 92.6%, and negative predictive value of 100% were calculated for rEPC1. On the other hand, commercial ELISA kit based on the native antigen B of Echinococcus granulosus had sensitivity of 96.2% and specificity of 96.8%. No significant difference was found for sensitivity or specificity between the rEPC1 and commercial kit. However, rEPC1 may be a valuable antigen for diagnosis of human CE.

Fascioliasis is a global parasitic disease that affects domestic animals and causes considerable economic losses in the process of domestic animal breeding in endemic regions. The cause of the disease involves a liver trematode of the genus Fasciola, which secretes materials into a host's body (mainly proteins) in order to protect it from the host's immune system. These materials can be involved in the migration, growth, and nutrition of the parasite. Among the expressive proteins of Fasciola, proteases have been introduced as the appropriate targets for diagnosis, treatment, and vaccination against parasites. Cathepsin L (CL) is a member of cysteine proteases; it is widely expressed in the Fasciola species. The aim of this study was to evaluate two synthetic peptides from F. gigantica CL1 for improving serological diagnosis of the Fasciola infection. Therefore, the potential diagnostic value of the surface epitopes of CL1 was assessed using ELISA. In the current study, bioinformatics tools were applied to select two appropriate epitopes of Fasciola Cathepsin L1 as synthetic antigens. Their diagnostic values were evaluated by two methods of indirect ELISA and dot blot analysis. The findings revealed that the first peptide at a dilution ratio of 1:400 and the second peptide at a dilution ratio of 1:100 had the best results and the best concentration of antigens was introduced at 4 μg/ml. Moreover, 191 sera samples were analyzed by both peptides by using the ELISA method, including fascioliasis sera, other parasitic sera and negative sera. The sensitivity of the peptides 1-ELISA and peptide 2-ELISA for the diagnosis of the various cases was 100%. The specificity of the first peptide was 87.3% and its efficacy was determined to be 93.65%. The specificity and the efficacy of the second peptide were 79% and 89.5%, respectively. The positive predictive values of the first and second peptides were obtained to be 86.27% and 79.27% respectively, and the negative predictive values of both peptides was calculated as 100%. In conclusion, the results of this study indicated that the peptide 1 from CL1 may be used as an appropriate antigen for the diagnosis of fascioliasis if the findings are backed up by using other serodiagnostic methods for checking serological cross-reactivity linked to other parasites.

The immunodiagnostic tests for cystic echinococcosis (CE) are mostly serological tests based on ELISA that use hydatid cyst antigens for primary screening because of its simple preparation and availability. The challenge to develop new serological methods (as compared to those based on the hydatid cyst fluid antigens) to meet the gold standard remains. Appropriate sources of antigenic material are necessary for application to improve the efficacy of immunodiagnostic tests at a population level. In the current study, a fusion protein containing the coding sequence of antigen B2t and two sequences of EPC1 antigen with some modifications was reconstructed. Using bioinformatics tools, these sequences were joined together by applying the sequence of a rigid α-helix-forming linker to obtain an appropriate structure of a fusion protein. Synthetic recombinant fusion protein was expressed using pET28a as a vector and evaluated by indirect ELISA test for sera from patients with hepatic CE and other parasitic infections. The sensitivity of the fusion protein was lower (88.46%) than the available ELISA kit (96.15%). However, the differences in sensitivity were not statistically significant as compared to the recombinant fusion peptide with the commercial kit (p = 0.269). The specificity of the recombinant fusion protein (95.45%) was not significantly lower than the commercial kit (96.59%; p = 1.000). Moreover, surprisingly there was no difference in the cross-reactivity values of performance between the recombinant-ELISA and commercial kit. The positive and negative predictive values of the recombinant antigen were achieved as 92% and 93.33%, respectively, while for the commercial kit, they were obtained as 94.33% and 97.70%, respectively. In conclusion, as an early evaluation of these antigens the performance of our recombinant fusion protein in ELISA is relatively promising. Although, it seemed that this peptide with specific antigenic epitopes might be more appropriate for the serological evaluation of CE by use of bioinformatics tools, our findings showed that cross-reactions and a negative reaction could occur in clinical performance. This fusion protein may have utility for diagnosis in humans, but further evaluation is needed using the WHO ultrasound classification for CE.

The present study aimed to determine the number of cases of animal fascioliasis per district in the southern littoral of Caspian Sea and to model suitable ecological niches for Fasciola infection in the region. Stool samples (n = 2688) were collected from cattle and sheep in Guilan, Mazandaran and Golestan provinces. The samples were tested using flotation method, and the number of parasite eggs per gram (EPG) of feces was recorded for each sample. Occurrence-only data of Fasciola were collected from the field. A total of 96 points/locations were used to model the ecological niche of Fasciola in maximum entropy (MaxEnt) and geographical information system (GIS). The spatial layers were compiled from 23 bioclimatic and biophysical variables for modeling analysis. Jackknife analysis was used to determine the relative importance of all variables in the model. In the present study, the proportion of fascioliasis in both hosts was highest in Guilan province (sheep: 12.34%, cattle: 15.16%), followed by Mazandaran (sheep: 7.3%, cattle: 6.25%) and Golestan (sheep: 0%, cattle: 0.94%) provinces. The Area Under Curve (AUC) value of the model was 0.909, indicating a good predictive power of the model. Our modeling results indicate that four variables, which were markedly incorporated into the model, are the major predictors of the presence probability of Fasciola spp. in the region: Bio17 (Precipitation of driest quarter; 45.5%), Bio14 (Precipitation of driest month; 24.8%), aspect (9%), and altitude (7.2%). The data presented herein show expansion of the potential high-risk areas of fascioliasis in the northern part of Iran, located at the southern littoral of Caspian Sea, especially in Guilan province. However, the extent of the predicted risk zones varied between the different areas of the region and within provinces, such that at the present, many parts of Golestan province are less environmentally suitable for Fasciola distribution than other areas in the region.

Bakgrund: Sjuksköterskan är den person som är närmast patienten, och är den som oftast är med när en patient avlider. De anhöriga som lämnas kvar drabbas alltid av förlusten efter en död, och det är sjuksköterskans ansvar att sköta omvårdnaden av dessa anhöriga. I Sverige dör årligen cirka 90 000 personer, varav 11600 räknas som plötsliga dödsfall. När döden kommer plötsligt orsakar den ett enormt trauma som riskerar att inverka negativt på de efterlevandes hälsa, om de inte får rätt omhändertagande. Syfte: Syftet med studien var att identifiera och beskriva sjuksköterskans bemötande av anhöriga som förlorat en familjemedlem i plötslig död. Design: Allmän litteraturstudie med systematiskt tillvägagångssätt. Metod: Litteratur söktes i databaserna CINAHL, PubMed, PsychINFO, Scopus, Eric och Swemed+. Under sökningen användes svenska Mesh-termer, booleska söktermer, fri sökning och thesaurus-sökning. 16 artiklar kvalitetsgranskades, varav 13 artiklar gick vidare för analys. Av dessa var 12 av kvalitativ art, och en av kvantitativ. Resultat: Bemötandet av anhöriga innefattar många områden. Följande huvudkategorier identifierades: Egenvård, att skapa en relation, att ge utrymme, att delge, att vara professionell, samt att lämna situationen. Konklusion: Då en patient har avlidit är det viktigt att sjuksköterskan är kompetent att ta hand om de sörjande anhöriga. Sjuksköterskan behöver vara relationsfokuserad i sitt bemötande av dessa, för att kunna se deras behov och ge dem rätt omvårdnad. De anhöriga är i akut behov av information för att skapa sig en förståelse och acceptans för det plötsliga dödsfallet.

Five species of nematodes and cestodes were collected from alimentary canals of pigeons: the nematodes were two species: Ascaridia colombae (16.66%) and Hadjelia truncata (1.96%), while the cestodes were Cotugnia digonopora (13.79%), Raillietina magninumida (18.62%) and Raillietina achinobothridia (32.35%); fecal examination revealed: Eimeria spp. (40.19%) and Cryptosporidium oocysts (2.94%); and blood smears showed: Haemoproteus cloumbae (47/05%); in mouth, throat and larynx: Trichomonans gallinae (57.84%); four species of ectoparasites were collected from feathers and subcutaneous nodules as follows: feathers: Pseudolynchia canariensis (63.72%), Columbicola columbae (79.41%), Menopen gallinea (44.11%); subcutaneous nodules: Laminosioptes cysticola (1.96%). From the parasitic fauna identified in this study, it is imperative to institute an integrated parasitic control through constant changing of litter, regular use of antihelminthics, anticoccidials and dusting of birds with pesticides.

A cross-sectional study was conducted during four seasons from October 2009 to October 2010 to assess the status of cystic hydatidosis in the slaughtered camels at Kerman abattoir. Hydatid cyst count and characterization were conducted based on routine meat inspection. Out of the total 217 camels examined visually and manually by palpation and incision, 45 (20.73%) were found harboring hydatid cysts. A significantly higher infection was detected in older camels (P

Problem statement: The Linguatula serrata is one of the parasitic zoonoses. Human beings may also be infected by both the nymph stage, a condition called nasopharyngeal linguatulosis or Halzoun syndrome and the egg, a condition called visceral linguatulosis. Approach: The aim of the present study was to evaluate the prevalence of nymphal stages of L. serrata in mediastenal and mesenteric lymph nodes of cattle slaughtered in Kerman slaughterhouse, south east of Iran. For this purpose, mesenteric and mediastenal lymph nodes of 450 cattle of different sex and age were examined. Results: A prevalence of 16.22% was observed in mesenteric lymph nodes. Higher prevalence of infection was observed in animals aged above four years and during autumn season. The infection rate increased with age (p

A survey was carried out to investigate the prevalence of hard tick species (Acari: Ixodidae) on cattle and sheep southeast of Iran. A total of 972 ticks were collected from 280 infested cattle and 1,207 ticks were collected from 632 infested sheep during activating seasons of ticks in 2008-2009. The species collected from cattle were Hyalomma marginatum marginatum (50.92%), Hyalomma anatolicum excavatum (25.61%), Hyalomma anatolicum anatolicum (8.12%), Hyalomma asiaticum asiaticum (1.85%), and Rhipicephalus sanguineus (13.47%) while the species collected from sheep were R. sanguineus (36.37%), H. marginatum marginatum (30.65%), H. anatolicum excavatum (19.05%), H. asiaticum asiaticum (10.52%), Hyalomma detritum (3.14%), and Dermacentor marginatus (0.24%). The results show that, H. marginatum marginatum, H. anatolicum excavatum, and R. sanguineus are dominant tick species in the surveyed area.

This research was carried out in order to detect the prevalence of nymphal stages of Linguatula serrata in mediastinal and mesenteric lymph nodes of sheep slaughtered in Kerman slaughterhouse, southeast of Iran. For this purpose, mesenteric and mediastinal lymph nodes of 806 sheep of different sex and age were examined. One hundred and thirty out of 806 (16.1%) of the sheep were found positive for L. serrata infection. The infection rate increased with age (P 0.001). Prevalence of L. serrata nymphs in males and females and different seasons was not significantly different (P 0.05). Considering the results, it could be concluded that the prevalence of L. serrata in sheep of Kerman is high and plays an important role in epidemiology of linguatulosis. The zoonotic potential of this parasite to human health is discussed.

To evaluate the prevalence of nymphal stages of L. serrata in mesenteric lymph nodes of camels slaughtered in Mashhad slaughterhouse, Northeast of Iran.For this purpose, mesenteric lymph nodes of 400 camels of different sex and age were examined. The lymph nodes were examined macroscopically and a digestion method was also applied for investigation of samples which was negative macroscopically.The mesenteric lymph nodes of 73 camels out of 400 (18.25%) were infected by L. serrata nymphs.Prevalence of L. serrata nymphs in males and females and different age was not significantly different (P0.05), but difference was observed between the prevalence in different seasons (P0.05). The potential importance of these findings to human health is discussed. This is the first report of infection with L. serrate of camels in camels slaughtered at northeast of Iran.

The primary objective of this study was to determine the diversity and intensity of ticks found on camels (Camelus dromedarius) and their seasonal population dynamics in Kerman, southeast of Iran. For this purpose, a total of 426 tick specimens were collected from 217 infested camels in southeast of Iran during activating seasons of ticks (April 2009 to March 2010). The species collected from camel were Hyalomma dromedarii (84.7%), Hyalomma marginatum (8.7%), Hyalomma anatolicum excavatum (5.4%), and Hyalomma anatolicum anatolicum (1.2%). The highest seasonal activities occurred in summer. The ratio of male ticks was more than female ticks. H. dromedarii was the predominant tick species and accounted for 84.7% of the ticks.

Linguatula serrata is one of the zoonotic parasites. The aim of this study was to evaluate the prevalence of nymphal stages of L. serrata in mesenteric and mediastinal lymph nodes of goats slaughtered in Kerman slaughterhouse, southeast of Iran. For this purpose, mesenteric and mediastinal lymph nodes of 407 goats of different sex and age were examined, revealing an infection prevalence of 49.1%. The prevalence of L. serrata infection among goats is higher than previously reported from Iran and indicates a strong focus of infection in goats. The infection rate increased with age (P0.05). Further, the prevalence of L. serrata nymphs in different seasons was significantly different (P0.05), but no significant difference was observed between the prevalence in males and females at the same age (P0.05). The potential importance of these findings to human health is discussed.
