摘要
为了解2021年新疆部分地区猪群中伪狂犬病病毒(PRV)野毒感染情况和免疫抗体水平,试验应用PRV-gE和PRV-gB蛋白抗体检测试剂盒对新疆5个地区9个规模化养猪场的580份血清样品分别进行了PRV-gE和PRV-gB两种蛋白的抗体检测。结果发现,2021年新疆部分地区猪群PRV-gE抗体平均阳性率为28.28%(164/580),不同地区之间、不同猪场之间的PRV-gE抗体平均阳性率差异较大;PRV平均免疫抗体阳性率为61.9%(359/580),低于国家规定标准(70%),仅有22.22%(2/9)猪场的免疫抗体阳性率达到了国家规定标准,不同地区之间、不同猪场之间的PRV免疫抗体阳性率差异较大。结果表明,2021年新疆部分地区猪群PRV野毒感染率仍处于较高水平,免疫合格率相对较低,需要重视该病的防控工作。
In order to understand the level of of pseudorabies virus(PRV)immune antibodies and wild virus infection in pig herds in some areas of Xinjiang in 2021,580 blood samples from nine large-scale pig farms in five regions of Xinjiang were tested for PRV-gB and PRV-gE antibodies by using the detection kit for PRV-gB and PRV-gE antibodies.The results showed that in 2021,the average positive rate of PRV-gE antibody in pig herds in some regions of Xinjiang was 28.28%(164/580),and the average positive rate of PRV gE antibody varies greatly between different regions and different pig farms.The average positive rate of PRV immune antibody in pig herds in some areas of Xinjiang was 61.9%(359/580),which was lower than the national standard(70%).Only 22.22%(2/9)pig farms had reached the national standard,and the positive rate of PRV immune antibody among different regions and different pig farms was significantly different.The results showed that in 2021,the infection rate of PRV wild virus in some areas of Xinjiang was still at a high level,and the qualification rate of immunization was relatively low.Therefore,attention should be paid to the prevention and control of the disease.
