 Abstract 


Cross-sectional study was conducted from October 2017 to February 2018 to determine the prevalence status of bovine trypanosomosis in Itang special and Gambella woredas, Gambella region of south west Ethiopia and to assess associated risk factors of the disease. Blood samples were collected from 384 randomly selected cattle of the study areas and evaluated through standard parasitological and haematological methods. The overall prevalence of trypanosomosis was 17.2%, (95% confidence interval (CI) 8.79-24.75). The most common trypanosome species identified were T. congolense (51.51%) followed by T. vivax (39.39%), T. brucei (27.72%) and mixed (7.58%) infections, respectively. Disparity in the prevalence of trypanosome infection was recorded in the different woredas, between the two sexes and body condition and the difference was not statistically significant (p > 0.05). Univariable logistic regression analysis showed that anaemic (PCV < 24%) had 0.881 times the risk of being trypanosomosis positive compared with non-anaemic animal (> 24) (OR = 5.7, 95% CI 2.77-11.77).Statistically significant difference (P= 0.001) was observed with the mean PCV values between aparasitaemic (24.92 ± 0.32SE) and parasitaemic animals (21.94 ± 0.29). In conclusion, this study revealed that trypanosomosis poses a threat to cattle production in the districts. Hence, appropriate disease prevention and control methods should be implemented to improve livestock production and agricultural development in the area.
