The specimens from 32 aborted fetus and 274 aborted cows were collected in 168 farms of Chonnam province from 2005 to 2008 and were tested the brucellosis. The results obtained are summarized as follows. In the 32 aborted fetus, bovine brucellosis was detected in 12 heads (37.5%), bovine viral diarrhea-mucosal disease was detected in 7 heads (19%), ainovirus infection was detected in 1 head (3.1%), and multi-infection of BVD and brucellosis was not detected, respectively. In the 306 cases of aborted fetus and cows, bovine brucellosis was detected in 44 heads (14%). Status of abortion were confirmed in 63 farms (38%) out of 168 farms from June to August. From the point of raising scale, studies found that 128 farms (76%) out of all raised under 20 heads. The incidence of abortion by brucellosis was mainly showed in 30 heads (68.1%) about 151~250 days of gestation. In the result of the 18 farms survey, the causes of infections were detected movement of infected cattle in 5 farms (28%), unknown cause in 12 farms (67%), and recurrence in 1 farm (5%). The results of this study suggest to take an advantage of the prevention and fundamental research for bovine brucellosis in Chonnam province.
