A cross sectional study was conducted from October 2013 to April 2014 to determine the seroprevalence of brucellosis and associated risk factors in small ruminants in Jibat district of west shoa zone. Small ruminants were selected randomly, from purposively selected district. A total 308 blood samples were collected from local breeds of sheep and goats and serum samples from these animals were initially screened by Rose Bengal Plate Test (RBPT) and those samples found positive by RBPT were further tested by Complement Fixation Test (CFT) for confirmation. Out of the total collected serum samples, 9 (2.92%) of them were positive when they screened by RBPT. Among the 9 positive serum samples, 4 of them were confirmed as Brucellaantibodies positive by CFT. Thus the overall seroprevalence of sheep and goats brucellosis in the study area was 1.29% (4/308). None of the risk factors studied had significant effect on the sero prevalence of the disease in study animals (P > 0.05). Key words: Brucellosis, CFT, Jibat, RBPT,Seroprevalence, Small Ruminant.
