Trypanosomosis is an economically important disease that has raised great and diverse kinds of research using different types of animals. Hence, this study is aimed at determining the better laboratory animal between the Swiss albino mice and Wistar albino rats in Trypanosoma brucei brucei studies. This study assessed the pathogenesis of T. b. brucei in Swiss albino mice and Wistar albino rats by probing the level of parasitemia, mean temperature, mean weight, hematological and histopathological parameters caused by the hemoprotozoan. Twenty laboratory animals, of mice (10) and rats (10) were grouped in two (control (5) and infected (5)), with the infected group inoculated with the blood protozoan intraperitoneally. Trypanosoma b. brucei was detected in the blood of both laboratory animals on day one post-infection, with all the infected animals dying between day seven and eight post-infection. The protozoan exerted a significant (p < 0.05) effect on the mean temperature, mean weight, and hematological parameters of the infected animals. Pathological effects of T. b. brucei infection were seen in the liver and lungs of mice, and the liver, lungs, kidney and spleen of rats. The pathogenesis of T. b. brucei was more severe in rats compared to mice based on the studied parameters. These findings showed that rats are better candidates for T. b. brucei studies.

Background and Aim: Helminth infections are one of the greatest causes of productive and reproductive loss in animals and man, and in some cases, it results in heavy mortalities. This study was conducted to determine the prevalence, species diversity, patterns of infections and risk factors associated with helminth infections of cattle in Ilorin, Nigeria. Materials and Methods: A total of 478 fecal samples were collected from abattoirs and cattle farms over a year period (March, 2018-February, 2019). Fecal samples were visually examined then observed using simple flotation and formalin-ethyl acetate sedimentation techniques. Eggs and worms were identified according to standard procedures. The packed cell volume was determined using the hematocrit centrifugation technique. Results: A total of 79.92% of the cattle examined were found positive with one or more helminth species. Eighteen helminth species (cutting across all classes of helminths) were detected, with Haemonchus contortus (60.46%), Trichostrongylus spp. (46.44%), Ostertagia ostertagi (42.05%), Bunostomum phlebotomum (28.87%), Cooperia spp. (24.27%), Oesophagostomum radiatum (21.97%), Strongyloides papillosus (12.13%), and Fasciola gigantica (10.67%) been the most prevalent. Helminth infection was detected all through the year with the least prevalence recorded in February (55.00%). About 61% of the examined cattle harbored double/multiple helminth species. There was a significant difference between breed, sex, physiological status, and season with the prevalence rate of helminth infections (p

Objective: The current study aimed to determine the prevalence, infection burden, and risk factors associated with the occurrence of gastrointestinal (GI) parasites in different avian species in Ilorin, Nigeria. Materials and Methods: This study was conducted in Ilorin, involving 597 fecal samples and GI tracts from a variety of sold and slaughtered avian species. The study was conducted between September 2017 and February 2018. Fecal samples were examined using floatation technique, while the GI tracts were examined for gross helminths and its content were subjected to the direct wet mount examination. Data were analyzed using percentages (descriptive) and the Chi-square (χ2 ) test (inferential). p < 0.05 was considered significant for all analysis. Results: Ten GI parasites were detected with Eimeria species (32.83%), Ascaridia galli (30.15%) and Heterakis gallinarum (24.79%) as the most prevalent ones. Multiple parasites co-infection was recorded in all the avian species: broilers (77.78%), layers (33.33%), cockerels (45.16%), indigenous chickens (17.91%), ducks (69.70%), pigeons (94.12%), turkeys (47.83%), and guinea fowls (77.36%). Pigeons (100.00%) and turkeys (95.65%) were the most infected avian species. Age, sex, and avian types were significantly (p < 0.05) associated with the occurrence of GI parasites infection. Conclusion: This study gives a reflection of the GI parasites fauna of avian species in Nigeria. The GI parasites are endemic among different avian speciesin Ilorin, North Central Nigeria. Knowledge on the epidemiology of these parasites is important in instituting a good preventive and control measures against GI parasites, so as to have maximum production and reproduction effects in the poultry industry.

Aim: Helminth infections inflict negatively on the production and well-being of animals including poultry. This study was carried out to determine the prevalence, species diversity, intensity, and risk factors associated with the gastrointestinal helminths of intensively raised poultry in Kwara Central senatorial district of Kwara State. Materials and Methods: Fecal samples were collected from 502 poultry species from 15 farms. The samples were subjected to floatation and the formalin-ethyl acetate concentration techniques of examination. The intensity of infections was determined using McMaster counting technique. Results: Seven helminth species were detected with Heterakis gallinarum (10.2%) and Ascaridia galli (6.0%) been the most prevalent, while Capillaria species was the least prevalent (0.8%). Physiological status, bird type, production purpose, farm age (years), presence of other animals in the farm, flock size (birds), farm size (acres), housing type, farm type, frequency of anthelmintic use, distance to waste area (meters), level of biosecurity, and frequency of cleaning the pen were the risk factors significantly (p

Parasitism is of great concern to the production, reproduction and performance of man and animals. The present study evaluated the parasitic conditions of rabbits brought for medical attention in the major Veterinary hospitals in Osun State, Southwestern Nigeria during ten years (2006–2015). A total of 444 rabbits were brought during the study period, out of which 312 (70.27%) was diagnosed for mange, 126 (28.38%) for helminthoses, 60 (13.51%) for coccidiosis and 6 (1.35%) for flea infestation. There was no defined pattern in the yearly and monthly prevalence of these parasitic diseases. Age, sex and season were the statistically significant (P
