Investigation of bovine brucellosis in the Northeastern Turkey.
Bovine brucellosis, caused by Brucella abortus, is a significant problem for both public and animal health in Turkey. This study was conducted on the calving seasons between 2001 and 2006. A total of 626 serum samples of cattle obtained from 27 herds with a history of abortions was examined for Brucella antibodies by RBPT, SAT and ELISA. Of the cattle sera analysed, 221 (35.30%) and 206 (32.92%) and 247 (39.45%) were found to be positive by RBPT, SAT and ELISA, respectively. B. abortus was isolated from 48 (32.21%) of 149 lung samples and stomach contents of the aborted fetuses. Based on the biochemical tests and the agglutination tests with monospecific A and M antisera, only 3 of the isolates were found to be B. abortus biotype 1 and the remaining 45 were biotype 3. This study also revealed that the dominant biotype of B. abortus was biotype 3 in this region. The determination of the agents responsible for bovine brucellosis and serosurvey of this disease are expected to help better understanding of this zoonotic infection in this region and neighbouring countries.
