| Sumario: | Debela Abdeta Efa School of Veterinary Medicine, Wollega University, Nekemte, EthiopiaCorrespondence: Debela Abdeta EfaSchool of Veterinary Medicine, Wollega University, Nekemte, EthiopiaTel +251913125925Email debela.abdeta@gmail.comBackground: Bovine trypanosomosis remains a vital livestock disease and constraint which is intimidating livestock health and production, regardless of ongoing tsetse and trypanosomosis control struggles in Jimma Arjo district, East Wollega zone, Ethiopia.Methods: A cross-sectional study was carried out with the objective of determining prevalence of cattle trypanosomiasis and apparent tsetse fly density in six randomly selected peasant associations of Jimma Arjo District from April 2018 to January 2019.Results: From overall 819 arbitrarily selected cattle (n= 36; 4.39%), infection rate was recorded. Selected animals were invariably infested with different trypanosome species among which Tryapanosoma congolense (80.55%) was the most common, followed by T. vivax (11.11%), T. brucei (5.55%) respectively. Co-infection of T. vivax and T. congolense accounted for 2.77% of total infection rate. This finding indicates a statistically significant difference (p< 0.05) among good, medium, and poor body condition animals with respect to Tryapanosomosis infection rate. Poor body condition animals were highly infected with trypanosome parasite as compared to medium and good body condition score animals. This study shows statistically significant association was obtained between mean packed cell volume (PCV) and trypanosomiasis infection rate (P< 0.05). The lower mean PCV value (21.14%) were highly affected as compared with high mean PCV value animals (25.26%). The result of entomological survey, by using mono pyramidal traps deployed near animal grazing field and rivers of selected peasant association (PA), showed presence of four Glossina species namely Glossina morsitans, G. pallidipes, G. tachinoides, and G. fuscipes with high fly density per trap in Meta PA. Higher catches of G. fuscipes were registered as compared to other vectors.Conclusion: Generally, this study indicated the disease is still a main problem for livestock health and production in the study area and it necessitates disease and tsetse fly control.Keywords: bovine trypanosomiasis, buffy coat, Jimma Arjo, prevalence, tsetse flies |
