The study was conducted in a herd (n: 244) in which goats (n: 206) and sheep (n:38) had a history of brucellosis in Bursa which is located in Northwestern of Turkey between the years 2012-2014. For the detection of Brucella spp. and the other zoonotic bacterial agents, semen samples were taken from Saanen goats (n: 35) and rams (n: 8). Samples were tested by routine diagnostic procedures and PCR. The serum samples of male animals were also tested for Brucellosis by C-ELISA and I-ELISA. The culture results represented Trueperella pyogenes (n:2), Pasteurella pneumotopica (n: 5), Esherichia coli (n: 3), Aeromonas salmonicida subs. Salmonicida (1), Brevundimonas vesicularis (n: 2) and Mycoplasma bovigenitalium (n: 1) and Mycoplasma arginini (n: 1) from semen samples. Rams had no symptoms due to epididymitis or epididymoorchitis in clinical examination, but two bucks showed orchitis and they were serologically positive for brucellosis. Also, one seronegative buck showed epididymitis in a flock. There were no statistically significant differences between the serologically positive and negative animals in an examination of semen samples in terms of their volume, concentration, mass activity, motility and defectivity rate for acrosome. Although 20 of the serum samples were negative for anti-Brucella antibody, 23 of them were serologically positive for brucellosis. As a result of this study, Brucellae were not detected by bacteriologically and molecularly while there were some positive serum samples for brucellosis. This could be attributed that these samples might have been collected from chronically infected animals in which animals generally do not shed the organisms. Therefore, it was thought that sampling with regular intervals might help for the definitive incidence of brucellosis.
