新疆阿克苏地区部分猪场伪狂犬病病毒gE蛋白抗体ELISA检测与分析

ELISA Detection and Analysis of Pseudorabies Virus gE Protein Antibodies in some Pig Farms in Aksu Region of Xinjiang

为初步了解2019年新疆阿克苏地区部分规模化养殖场猪伪狂犬病毒(PRV)野毒感染情况,本试验采集了阿克苏地区6个猪场血样644份,采用间接ELISA方法检测猪PRV-gE蛋白的抗体情况。结果显示:6个猪场A-F中,E场的gE蛋白抗体阳性率最高为6.38%(3/47),A场、C场和F场的gE蛋白抗体阳性率最低都为0,其平均抗体阳性率为2.48%;对不同年龄的猪群分析,PRV-gE蛋白的阳性率最高为仔猪2.78%,最低为种公猪1.52%。试验表明,阿克苏地区依然存在猪伪狂犬病毒野毒的感染。

In order to preliminarily know the infection situation of Pseudorabies Virus(Pseudorabies Virus,PRV)in some pig farms in Aksu region of Xinjiang in 2019,644 blood samples were collected from six pig farms in Aksu region,and the antibody status of PRV-gE protein in swines was detected by indirect ELISA method.Results showed that the highest positive rate of field E was 6.38%(3/47),the lowest positive rate of field A,C and F was 0,and the average antibody positive rate was 2.48%;Analysis of pig populations at different ages,the highest positive rate of PRV-gE protein was 2.78%in piglets,The lowest boar was 1.52%.These results indication that infection of swine pseudorabies virus were still exists in Aksu ares of XinJiang.
