摘要
为了解南京市猪伪狂犬病野毒感染情况,2015年对南京市40个猪场660份猪血清进行了伪狂犬病毒gE抗体监测和分析。结果显示,全市共发现7个抗体阳性猪场,场阳性率为17.50%;共检出gE抗体阳性血清31份,抗体阳性率为4.69%。经产母猪gE抗体场阳性率最高,达28.57%,血清gE抗体阳性数占总数的8.57%;而8个后备母猪场均没有检测到gE阳性抗体;断奶前仔猪的gE抗体阳性也相对较低。结果表明,南京市猪场仍有伪狂犬野毒感染或因母本感染野毒导致母源抗体的存在。
In order to understand the status of wild pseudorabies virus（PRV）infection of pigs,660 serum samples from 40 pig farms in Nanjing city were investigated for detection and analysis on antibodies against glycoprotein E（gE）of PRV in 2015.The results showed that 31 samples from 7 pig farms were positive for g E antibodies,the farm positive rate was 17.5%,and the antibody positive rate was 4.69%.Furthermore,the farm positive rate and antibody positive rate of multiparous sows were 8.57% and 28.57% respectively.No sample was found in farms of replacement gilts and the g E antibody rate of piglets before weaning was relatively low.The results indicated that there was wild virus infection or maternal antibodies of PRV in sows in Nanjing pig farms.
