摘　　要：为了解湖南省规模化猪场猪伪狂犬病免疫状况及猪伪狂犬病毒感染情况,2018年在湖南省14个市州208个规模猪场采集4288份猪血清,采用ELISA方法检测血清中的伪狂犬病毒抗体。结果显示,免疫猪PRV gB抗体个体阳性率为78.1%,PRV gE抗体个体阳性率为21.0%,场阳性率为38.9%;从不同养殖规模来看,存栏量在1000头以上的大型猪场PRV gE抗体阳性率最高,为22.9%;在季节分布上,夏季猪群的PRV gE抗体阳性率最高,为25.1%;在不同的年龄阶段中,以种母猪PRV gE抗体阳性率最高,为36.2%。表明猪伪狂犬病在湖南地区仍广泛流行,野毒感染情况较为普遍。Serological investigation was carried out to understand of the immunization and infection status of porcine pseudorabies virus(PRV)in scaled pig farms of Hunan province.4288 serum samples were collected in 208 different scale pig farms in 2018.ELISA method was used to detect PRV antibody in serum samples.The results showed that:the positive rate of PRV gB antibodies in immunized pigs was 78.1%,the positive rate of PRV gE antibodies was 21.0%,and the positive rate of pig farms was 38.9%;In different scale farms,large farms with more than 1000 stocks,the positive rate of PRV gE antibodies was the highest,which was 22.9%.In different quarters,the positive rate of PRV gE antibodies in summer was the highest,which was 25.1%.in different herds,the positive rate of PRV gE antibodies was the highest,in sows which was 36.2%.It indicated that porcine pseudorabies is still widely prevalennt in Hunan,and wild-type virus infection is more common.
