用试管凝集法(SAT)、间接血凝抑制试验(IHA)和酶联免疫吸附试验(ELISA)三种方法，对来自青海省湟中县田家寨镇某奶牛场发生过流产群的95份奶牛血清，进行布氏杆菌病、衣原体病和弓形虫病的血清学调查.结果：检出布氏杆菌病阳性血清1份，衣原体阳性血清15份，弓形虫阳性血清2份，血清阳性率分别为1.05%、15.79%和2.11%.初步说明引起该牛场流产的病因为布氏杆菌病、衣原体病及弓形虫混合感染.%　　95 Serum samples collected from abortion cows in a dairy farm in Huangzhong County,Qinghai Province were tested for specific antibodies against Brucella meliten,Chlamydia psittaci and Toxoplasma gondii with SAT,IHA and ELISA with corresponding antigens. The results showed that 1,15 and 2 serum samples were positive for Brucella meliten,Chlamydia psittaci and Toxoplasma gondii respectively with,the positive rates of 1.05%,15.79% and 2.11% suggesting that cows in the farm had been infected with Brucellosis,Chlamydiosis and Toxoplasmosis.
