This study aims at determining the seroprevalance of Coxiella burnetii in cows, sheep, goats and staff, working in the stock breeding sector in Diyarbakir region. Therefore, C. burnetii antibodies were investigated in sera samples of 612 sheep, 700 goats, 584 cows and 90 staff by enzyme-linked immunosorbent assays (ELISA). In the study, seropositivity was obtained as 25.4, 38.6, 20.0 and 6.6% in sheep, goats, cows and stockbreeding staff, respectively. Consequently, C. burnetii seropositivity, whether in people or in animals, had a ratio that should not be ignored in Diyarbakir region. Abort cases in ruminant should be assessed from the viewpoint of Coxiellosis. Also, people, especially those who are in risk group, should be made to be conscious of Coxiellosis infection, and measures for preventing this illness should be taken.
