This study aimed to determine the prevalence of ovine brucellosis in the states of Rio Grande do Norte, Paraíba, and Sergipe. A seroepidemiological survey was carried out in 121 properties under 23 municipalities between 2011 and 2012. The 1,034 serological samples collected from the sheep were subjected to the agar gel immunodiffusion (AGID) test using kits produced by the Paraná Institute of Technology (TECPAR). Anti-Brucella ovis antibodies were observed in 5.37% (70/1,304) of the animals evaluated, and the difference in the incidence of brucellosis between the adults and young animals of both sexes, and between the males and females was statistically significant (p < 0.05). The prevalence of brucellosis in Rio Grande do Norte, Paraíba, and was Sergipe 7.66% (36/470), 5.40% (13/241) and 3.54% (21/593), respectively. Of the municipalities visited, 91.30% (21/23) harbored herds with positive serology, and 42.15% (51/121) of the properties had at least one seropositive animal. The lack of training among the workers (p ? 0.05) (odds ratio = 3.68; 95% CI = 1.08-12.60; p = 0.038) was identified as a risk factor. The results obtained in this study indicate that the sheep from Rio Grande do Norte, Paraíba, and Sergipe are infected by B. ovis, thus necessitating the adoption of proper sanitary measures for preventing the spread of the disease in the herds.
