2015年安徽省部分中小规模猪场猪伪狂犬病定点监测

摘要

为了解安徽省中小规模猪场猪伪狂犬病病毒gE和gB免疫抗体情况，设立3个固定监测点，每个点选取4个规模猪场进行监测。应用 ELISA，对12个猪场578份血清开展 PRV gE 和 PRV gB 抗体检测。结果表明，在12个不同规模猪场中，58．3％的猪场都存在不同程度的感染。578份血清样本中，gE 抗体总的阳性率20．4％，免疫抗体阳性率为72．1％。表明安徽省中小规模猪场 PRV 隐性感染率较高，并且免疫抗体合格率不高。%A surveillance was conducted to understand the sero-positive rates of PRV gE and gB antibodies. 4 scaled pig farms in each 3 counties in Anhui province were chosen as fixed monitoring points.578 serum samples were collected form 12 pig farms for PRV gE and gB antibody test by ELISA.The herd positive rate of PRV gE was 58.3% in these 12 farms,with the total positive rate 20.4%.The total positive rate of PRV-gB antibody was 72.1%.The results showed that the PRV inapparent infection rate was high,and the immune antibody qualified rate was not so high.
