Brucellosis is one of the important zoonotic diseases among livestock. This study was carried out to estimate the prevalence of brucellosis and isolate Brucella spp. in sheep in Kassala State in the east of Sudan. Two thousand and five serum samples were randomly collected from nine different localities. All serum samples were examined by the Rose Bengal plate test (RBPT) and the modified RBPT (mRBPT). Forty-three (2.15%, 95% confidence interval [CI]: 1.6, 3.0) and 68 (3.4%, 95% CI: 2.6, 4.2) samples were positive with the RBPT and the mRBPT, respectively. According to a known diagnostic sensitivity of 86.6% and a known diagnostic specificity of 97.6% for the mRBPT, the true prevalence was estimated to be 1.2% (95% CI: 0.3, 2.2). Different tissue samples were collected from 41 mRBPT seropositive animals.
