cross-sectional study was conducted to determine the seroprevalence and associations with potential risk factors of brucellosis in indigenous cattle  breeds at the livestock-wildlife interface area of Yankari Game Reserve, Bauchi State, Nigeria. A total of 1000 sera samples were examined from 44 herds using convenient and simple random sampling technique. Rose Bengal Plate Test (RBPT) and competitive Enzyme-linked Immunosorbent  Assay (c- ELISA) were used as screening and confirmatory tests respectively. Of the 1000 samples, 23.5% samples were RBPT positive, and after the confirmatory test, the overall true animal level prevalence was 4.1%. For the herd level prevalence, (47.7%) herds had at least one animal that is seropositive following both tests. Brucellosis seroprevalence was significantly associated with the following potential risk factors; herds that belong to a cooperative society member (p?0.042), herds that keep only cattle (p?0.001), herds that practice commercial farming system (p?0.011), herds that possess a herd size of 51 to 100 cattle (p?0.009) and herds that have no history of abortion and other reproductive disorder (p?0.009). No statistically significant differences in brucellosis seroprevalence was obtained within sex, breed and age groups It can be concluded that brucellosis  is still endemic in the study area.
