Prevalence Of Bovine Trypanosomosis In Sokoru District, Jimma Zone, Oromiya Region, Southwest Of Ethiopia

摘要

The study was conducted to investigate the prevalence and magnitude of bovine trypanosomosis in selected villages of Sokoru District, Jimma Zone, Oromiya Region, Ethiopia, to assess and analyze the efficacy of trypanocidals in use, and the sustainable and effective control options of tsetse transmitted trypanosomosis.rnThe questionnaire survey revealed that trypanosomosis was the most important and major disease in the study area. Entomological survey revealed that Glossina m. submorsitans was the highly prevalent tsetse fly species followed by Glossina pallidipes. The apparent fly density tsetse was relatively higher in late rainy season at Abelty compared to Tiroshashama (0.194 and 0.028fly/ trap /day respectively). In Tiroshashama 0.017 fly /trap/ day of G. m. submorsitans and 0.017 G. pallidipes was caught in dry season whereas no fly was caught in Abelty. The prevalence of trypanosomosis was higher in dry season 8.36%, compared to 7.22 % in late rainy season. A significant difference (P< 0.05) was noticed between the mean PCV values in parasitaemic (95% Cl 21.24, 23.59) and aparasitaemic (95% Cl 23.93, 24.73) cattle. The result also indicated a better protection by Isometamidium chloride for prophylaxis of animal trypanosomosis in the study area.
