Sero-prevalence of brucellosis in extensively managed goats in Nyangatom District, South Omo zone, Southern Ethiopia

A cross-sectional study was carried out from March 2023 to March 2024 to assess the seroprevalence and risk factors of brucellosis in goats in the Nyangatom district, South Omo Zone, Southern Ethiopia. A total of 768 extensively managed local female goats of different age groups, were bled and data on hypothesized risk factors were collected using a semi-structured questionnaire. The preliminary screening of the sera for brucella antibodies was done using the Rose Bengal plate test (RBPT) and sera positive for RBPT were further examined by the complement fixation test (CFT). The overall seroprevalence of brucellosis was 12.9 . Among the risk factors considered, seroprevalence was associated with parity, litter size, flock size, and history of occurrence of abortion (p
