Use of the enzyme-linked immunosorbent assay for screening cattle for Brucella antibodies in Nigeria.
The prevalence of Brucella antibodies in settled Fulani cattle herds in Kaduna State, Nigeria, was determined by using the enzyme-linked immunosorbent assay (ELISA) technique. Out of a total of 762 animals drawn randomly from 40 cattle herds in various areas of the state, 50 (6.6%) tested positive. There was no significant difference (P<0.01) in the number of reactors between male and female animals. Brucella antibodies were detected in animals in all areas of the state but prevalence was highest in Kaura area (26.8%) and was lowest in Zonkwa area (1.0%). Out of the 762 animals, 23 (3.0%) tested positive in the agglutination test (SAT) while 16 (2.1%) tested positive in the Rose-bengal plate test (RBTP). This study indicated that cattle in Nigeria have antibodies to Brucella tested by ELISA technique and that seropositive animals are located in distinct foci. The identification of these pockets of infection on a nation-wide basis will be crucial for future brucellosis control programmes.
