摘要
为了了解海南规模化养猪场猪伪狂犬病毒(PRV)感染情况,为我省规模化猪场PRV净化提供帮助。本调查应用阻断ELISA方法对海南10个规模化养殖场的600份猪血清进行猪伪狂犬病病毒抗体血清学调查。调查结果显示:10个猪场600份猪血清样品伪狂犬病毒野毒(gE基因)抗体阳性率为13.33%,其中场点野毒抗体最低为0%,最高为51.66%,而母猪群阳性率为4%,公猪群为12%,仔猪群为9%,育肥猪群为37%;伪狂犬中和(gB基因)抗体阳性率为73.67%,其中猪场抗体最低为51.7%,最高为90%,而群体阳性率中母猪为97%,公猪为100%,仔猪为60.7%,保育猪为63%。调查结果表明,我省猪场存在野毒感染情况,PR免疫效果还有待进一步加强。
in order to understand the infection situation of pseudorabies virus(PRV)in large-scale pig farms in hainan province,it provides help for PRV purification in large-scale pig farms in hainan province.In this study,600 samples of pig serum from 10!large-scale farms in hainan were serologically investigated by blocking ELISA.The results showed that the positive rate of pseudorabies virus wild virus(gE gene)antibody in 600 samples from 10 pig farms was 13.33%,the lowest was 0%,the highest was 51.66%,and the positive rate of sows was 4%,boars 12%,piglets 9%and fattening pigs 37%.The positive rate of pseudorabies neutralization(gB gene) antibody was 73.67%,among which the pig farm antibody was 51.7%at the lowest and 90%at the highest,while the group positive rate was 97%in sows,100%in boars,60.7%in piglets and 63%in conservation pigs.The results showed that there were wild virus infection in pig farms in our province,and the immune effect of PR was still to be strengthened.
