A cross sectional study design was employed with the aim to determine sero-prevalence of brucellosis among sheep and goats and identify factors associated with sero-positivity to Brucella. A total of 558 sera were collected randomly and aseptically from small ruminants from November, 2015 till October, 2016 in Tselemti district, Northern Ethiopia, following proper restraining. All the sera were primarily screened for the presence of Brucella antibodies using Rose Bengal Plate test (RBPT) and then confirmed by Complement Fixation Test (CFT). The overall sero-prevalence of disease in the study area was 1.79% (n=10). Most of the risk factors including peasant association, species, sex, age, parity, herd size, lactation, and pregnancy status had no significant effect on the sero-positivity to Brucella (P>0.05), whereas animals with previous history of abortion and retained fetal membrane had significant effect (P<0.05). Hence, the odds of being sero-positive to Brucella was found to be 5.68 (COR=5.68; 95% CI: 1.13, 28.53) and 4.05 (AOR=4.05; 95% CI: 1.01, 16.22) times higher in animals with previous history of retained fetal membrane and abortion when compared with animal with no history of retained fetal membrane and abortion, respectively (P<0.05). The results of the current study demonstrated that brucellosis is endemic and the cause for reproductive loss and failure. Hence, the finding suggests that there is a need for implementation of better management practice such as culling of positive animals from the flock, burning/burial of aborted or retained fetal membrane, and also community awareness about zoonotic importance of the disease should be raised.
