Trypanosomiosis is an important parasitic protozoan disease of livestock in the area and causes severe disease which results in loss of livestock and agricultural productivity with serious socio-economic consequences. A cross-sectional study was conducted from June 2021 to November 2021 in selected kebeles in Ofa Wereda of Wolaita Zone with the objectives of determining the prevalence of trypanosomiosis and associated risk factors. Blood samples were collected from 280 selected cattle of the study villages and evaluated through standard parasitological methods. The overall prevalence was 15.00% (42/280). Trypanosoma congolense was the predominant species in the area (10.35%). Among species of trypanosomiosis, T. conglence and T. vivax were identified in 29 (10.35%) and 10 (3.57%) in examined samples respectively. Mixed infection by two species was noted in 3 (0.11%) of the samples. Meanwhile from considered epidemiological factors body condition and PCV-value were showed statistically significance difference (P < 0.05) with the overall prevalence of trypanosoma infections in cattle. On the other hand, trypanosoma infection among age, agro-ecology and sex showed no statistically significant difference (P > 0.05). In conclusion, bovine trypanosomosis is economically important disease that affects the health as well as productivity of cattle in Ofa Wereda. Hence, appropriate disease prevention and control methods should be undertaken to improve livestock production and agricultural development in the area.

abstract = {Trypanosomiosis is an important parasitic protozoan disease of livestock in the area and causes severe disease which results in loss of livestock and agricultural productivity with serious socio-economic consequences. A cross-sectional study was conducted from June 2021 to November 2021 in selected kebeles in Ofa Wereda of Wolaita Zone with the objectives of determining the prevalence of trypanosomiosis and associated risk factors. Blood samples were collected from 280 selected cattle of the study villages and evaluated through standard parasitological methods. The overall prevalence was 15.00% (42/280). Trypanosoma congolense was the predominant species in the area (10.35%). Among species of trypanosomiosis, T. conglence and T. vivax were identified in 29 (10.35%) and 10 (3.57%) in examined samples respectively. Mixed infection by two species was noted in 3 (0.11%) of the samples. Meanwhile from considered epidemiological factors body condition and PCV-value were showed statistically significance difference (P 0.05). In conclusion, bovine trypanosomosis is economically important disease that affects the health as well as productivity of cattle in Ofa Wereda. Hence, appropriate disease prevention and control methods should be undertaken to improve livestock production and agricultural development in the area.},
