中文摘要:
      为了解华东六省猪伪狂犬病病毒(PRV)感染情况,对2017年华东地区6个省份310家猪场送检的10 179份猪血清样品,应用PRV gE-ELISA抗体检测试剂盒进行感染抗体检测。结果显示:248 家猪场被检出PRV gE阳性抗体,场群阳性率为80.00%(248/310);4 546份血清样本被检出PRV gE抗体阳性,样本阳性率为44.66%(4 546/10 179)。对不同季节和不同饲养阶段样品的PRV gE抗体阳性率进行统计发现:春季样品阳性率最高,冬季偏低;种母猪样本阳性率最高,为60.59%,其次是经产母猪,种公猪最低。结果表明,华东六省猪群PRV野毒感染较为严重,尤其是母猪群。因此,这些省份应加大猪伪狂犬病的综合防控力度,重点关注种母猪群。
英文摘要:
      In order to recognize the infection status of pseudorabies virus(PRV)in pig farms located in six provinces of East China. In 2017,10 179 serum samples were collected from 310 farms and tested by PRV gE-ELISA kits. The results showed that,248 farms were detected positive for gE antibody,the positive rate at the farm level was 80.00%(248/310),while at individual level it was 44.66%(4 546/10 179). According to statistical analysis of infection rates in different seasons and stages,it was found that the positive rate was highest in spring and lowest in winter. Besides,the breeding sows had the highest positive rate,accounting for 60.59%,followed by multiparous sows,the breeding boars had the lowest rate. As a result,the infection status of wild PRV was serious in pigs in the six provinces of East China,especially in sows. For this reason,comprehensive prevention and control measures should be strengthened,and more attention should also be paid to sow herds.
