摘要
本研究对2010～2014年上海市36个规模猪场的8215份母猪血清样品进行伪狂犬病毒感染抗体检测,并对不同年份、不同区域、不同母猪存栏量的规模猪场伪狂犬病毒感染情况进行比较分析。结果显示,2010～2014年上海市规模猪场伪狂犬病毒感染抗体场阳性率为75%,母猪个体阳性率为46.40%（95%置信区间：34.18%～59.43%）,两者均呈现逐年上升趋势。从不同区域看,感染抗体阳性率以浦东新区、金山区、松江区和奉贤区较高,大型规模猪场（母猪存栏量〉1000头）伪狂犬病的防控成效较为显著。调查结果表明,上海市规模猪场母猪群伪狂犬病毒感染抗体阳性率较高,通过执行科学的免疫程序和构筑良好的生物安全环境对伪狂犬病防控起到良好效果。
Total 8215 sow serum samples from 36 scaled pig farms were collected from 2010 to 2014 for serological investigation into Pseudorabies virus（PRV） infection. The results were analyzed based on different years, regions and sow populations. The positive rate at herd level was 75% and individual level was 46.40%（95% CI： 34.18%～59.43%）. These data showed an increase trend in PRV infection year by year. Higher positive rates were observed in Pudong, Jinshan, Songjiang and Fengxian district than others. In addition, lower infection rates were detected on large scale pig farms（sow population 1000） than small farms, suggesting effect of better management on prevention and control.
