Aim this study was to determine the prevalence of brucellosis in various occupations in Northern State, Sudan, during 2012. A total of 753 serum samples (from 21 veterinarian, 39 meat inspectors, 407 abattoir workers and 286 animal handlers) in different localities were collected and screened for brucella antibodies by using Rose Bengal Plate Test (RBPT), Serum Agglutination Test (SAT) and 2 Mercaptoethanol Test(2MET). Then information's of occupation, age, sex, kind of work were recorded. Seroprevalence of brucellosis in veterinarians, meat inspectors, abattoir workers and animal handlers was 9.5%, 15.3%, 24.4% and 26.5% respectively. The variations in antibodies detected by RBPT, SAT and 2 ME test in the high risk individuals. Study documents the serological evidence of Br. abort infection in high risk groups in Northern State particularly in Sudan, where RBPT can be used successfully in hospitals as screening test.
