Prevalence and Risk Factors of Ovine Trichostrongylosis in Atbara Locality-River Nile State

Abstract

Across sectional study was conducted to determine prevalence of Trichostrongylus spp in sheep and to investigate some associated potential risk factors from June 2018 to April 2019 in Atbara locality, River Nile State. A total of 391sheep feacal samples were collected from abattoir(132animals), diseased animals in Atbara Veterinary Hospital (184animals) and some sheep farms(75 animals) ,They were examined by using direct flotation test for the presence of the parasite . The risk factors investigated were sex, breed, body condition, nutrition, age and season . The results revealed that the prevalence rate of trichostrongylosis in sheep was 31.7%.The questionnaire was used to determine the risk factors(sex ,age ,breed, body condition ,season , nutrition). The following risk factors showed association with sheep trichostrongylosis in the univariate analysis under significant level of p-value ≤ 0.25: sex (p-value = 0.000), breed (p-value = 0.448 ), body condition (p-value =0.000 ), nutrition (p-value = 0.331), age (p-value =0.194 ) and season (p-value =0.000) . Using multivariate analysis to determine possible significant association between Trichostrongylus and potential risk factors, the result showed that there was significant association with some of the investigated risk factors(sex, body condition and season) .It can be concluded that this Trichostrongylus parasite was prevalent in a high percentage in Atbara locality . As a trichostrongylosis is a zoontic disease its essential practices to cleaning and cooking of vegetables before used is required for prevention in human.
