2020年新疆地区猪繁殖与呼吸综合征病毒抗体检测与分析

为了解2020年新疆地区猪繁殖与呼吸障碍综合征病毒（PRRSV）抗体水平及其消长规律,本试验采用间接酶联免疫吸附试验（ELISA）法对1 218份血清中PRRSV免疫抗体水平进行检测和分析。结果显示,PRRSV抗体平均阳性率为78.49%（956/1218）,高于国家规定标准（70%）。S/P的平均值为1.22±0.84,变异系数为69.45%。不同类别猪群抗体平均阳性率在59.19%~91.50%之间,有一定的差异。在调查的10个规模化养殖场中,9个场PRRSV免疫抗体阳性率达到国家标准。不同类别猪群PRRSV变异系数较高,需进一步对现有的免疫程序进行调整和完善,确保各猪群健康。

Detection and Analysis of Antibodies Against Porcine Reproductive and Respiratory Syndrome Virus in XinJiang in 2020

In order to understand the level of porcine reproductive and respiratory disorder syndrome virus(PRRSV) antibody and its growth and decline in Xinjiang in 2020, this study used indirect enzyme linked immunosorptive assay(ELISA) to detect and analyze the PRRSV immune antibody levels in 1 218 serum samples. The results showed that the average positive rate of PRRSV antibody was 78.49%(956/1218), higher than the national standard(70%). The mean value of S/P was 1.22±0.84, and the coefficient of variation was 69.45%. The average positive rate of antibody in different pig groups ranged from 59.19% to 91.50%, with certain differences. In the 10 large-scale farms investigated the positive rate of PRRSV immune antibody in 9 farms reached the national standard. The variation coefficient of PRRSV was higher in different pig groups, so it was necessary to further adjust and complete the immunization program to ensure the healthy of all pig groups.
