A cross-sectional study was conducted in Wollega University Horro Guduru Animal Production and Research Center and its surrounding, of Western Ethiopia to estimate the seroprevelence of bovine brucellosis and its associated risk factors from December 2017 to March 2018. A total of 812 cattle from three stations (districts) were randomly selected for serology and questionery surveys from 102 respondents were collected using questionery format. All sample sera were screened by Rose Bengal Plate Test and positive samples were finally confirmed by competitive- Enzyme Linked Immuno-Sorbet Assay and Complement Fixation Test. Out of 812 samples tested, an overall seroprevalence of 0.73 (95% CI: 0.241-3.461) was recorded. The highest seroprevalence, 4.41% (95% CI: 0.028-3.473) was observed around Fincha district as compared to Horro Guduru Animal production center (0.31%) and Guduru district (0.99%). A Chi-square computed statistical analysis indicated that the origin (χ2=7.951: P<0.05), abortion history (χ2=8.217; P<0.050.), retained fetal membrane (χ2=36.47: P<0.001) and abortion time (χ2=9.756; P<0.05) were associated with increased prevalence of Brucella infection in the study areas. Moreover, retained fetal membrane was statistically identified as a common risk factor by logistic regression (OR=30.47, 95%CI) for brucellosis in cattle. The respondents indicated that only 38%, 18.18% and 30% of the farm owners in small, medium and large herd sizes were aware of brucellosis, respectively. The risk assessed indicates that using raw milk for human consumption has significant zoonotic importance. In conclusion, results of this study indicate the presence of Brucella infection and its risk factors in Horro Guduru animal production center of Western Ethiopia. These results prompt the need for further investigation and characterization the disease in order to prevent the infection and protect animals and people from contracting this economically important disease in the region.
