奶牛布氏杆菌病的血清学调查及分析

The Serological Survey and Analysis of Cows' Brucellosis

为了解奶牛布氏杆菌病的流行情况,及时消灭传染源,切断传播途径,2007年对本辖区的所有奶牛进行血清学调查。主要采用虎红平板凝集试验进行初筛,出现阳性及可疑再用试管凝集试验作进一步确诊。监测结果显示:对本辖区监测的724份奶牛血清样品中,平均阳性率为7.73%,阳性奶牛全部进行了扑杀并作无害化处理;布病在本辖区的个别奶牛场中阳性率高,在今后的一定时期内,需采取进一步的监测净化防控措施。

In order to understand the prevalence of cows＇ brucellosis, then to eliminate the source of infection and cut off the transmission in time, a serological survey of cows in the area has been held in 2007. RBPT was the chief way to screen the positive and suspicious samples, and then made fur- ther diagnosis by the SAT. The monitoring results indicate that： First, the average positive rate of the 724 cows＇ serum samples is 7.73%, the all posi- tive cows have been slaughtered with harmless treatment; Second, some dairy farms have a high positive rate, further prevention and control measures are need to be taken in future.
