2018年山东省猪伪狂犬病野毒抗体流行病学调查

Epidemiological investigation of swine serum antibody against gE of pseudorabies in Shandong Province in 2018

为了解2018年山东省猪伪狂犬病病毒(PRV)感染情况,对山东省99家猪场共2 240份血清样品进行了PRV gE-ELISA抗体检测。结果:猪场PRV gE抗体阳性率为82.83%(82/99),样本血清gE抗体阳性率为61.74%(1383/2240),而且春季样品阳性率最高,冬季较低。哺乳母猪血清阳性率最高,可达96.00%,其次是种公猪和后备母猪,表明该地区PRV野毒感染率依然较高,制定科学合理免疫程序并加强该病综合防控十分必要。

In order to know the infection of pseudorabies virus(PRV) in Shandong Province in 2018,2 240 swine serum samples were collected from 99 swine farms in Shandong Province and the anti-gE antibodies were tested using the PRV gE-ELISA antibody kit.The results showed that the positive rate of swine farms with anti-gE antibody was 82.83%.The positive rate of serum antibodies against gE was 61.74%.Moreover,those positive rates were the highest in spring and the lowest in winter.And the lactating sows had the highest positive rate of 96.00%,followed by the breeding boars and the replacement gilts.These data indicated that the virus infection was serious in Shandong Province.It is very important to design a scientific and reasonable immunization program and to take comprehensive measures to prevent and control this virus infection.
