摘要
为了解当前河南省猪伪狂犬病毒(PRV)野毒感染状况及总结评估有效的应对措施,利用g E-ELISA鉴别诊断试剂盒,对采集的900余份血清样品,进行了PRV野毒感染的血清学调查。同时针对一些代表性的猪场,进行长期的跟踪观察,评估PRV野毒感染的控制效果。结果显示,野毒感染血清阳性率为46.7%(427/915),猪场阳性率为76.7%(23/30),提示PRV在我省感染流行较为广泛。猪场跟踪显示,利用现有的疫苗,通过制定合适的免疫程序,在野毒感染的猪场依然可以生产出野毒阴性的上市商品猪,为现阶段猪伪狂犬的控制和净化提供了参考。
To investigate the current situation of porcine pseudorabies virus（ PRV） infection and evaluate the control strategy,we collected more than 900 serum samples from 30 large-scale pig farms and performed a serological survey using g E-ELISA kit. At the same time,we chose the representative farms to evaluate the effects of PRV prevention by Bartha-K61 vaccine immunization. The serological survey showed that the positive rate of g E-anbibody was 46. 7%（ 427/915）,and the percentage of PRV-positive pig farms was about 76. 7%（ 23/30）.The results indicated that PRV was epidemic in Henan province,but the PRV-g E negative fatten pigs can be produced in PRV-contaminated pig farms with reasonable immunization. It suggests that the Bartha-K61 vaccine is still efficient. The study provides a very useful reference for the prevention and eradication of PRV infection.
