2022-2023年新疆部分地区猪圆环病毒2型抗体检测及分析

Detection and analysis of porcine circovirus type 2 antibody in some areas of Xinjiang from 2022 to 2023

研究旨在了解2022—2023年新疆部分地区猪圆环病毒2型(PCV2)的抗体水平,以期为该病的科学防控提供参考。试验采用间接酶联免疫吸附试验(ELISA)对来自3个地区11个猪场的296份血清样品进行PCV2抗体检测。结果显示,PCV2抗体平均阳性率为85.47%(253/296),高于国家规定标准(70%);在调查的11个规模化猪场中,除A场和C场的PCV2抗体水平未达到国家规定标准外,81.82%(9/11)的猪场PCV2抗体水平均达到群体免疫的抗体水平和免疫标准。研究表明,新疆地区猪场PCV2的整体免疫效果较好,但部分猪场的PCV2抗体水平较低,需要对现有免疫程序进行调整和完善,确保各猪群健康。

The study aimed to understand the antibody levels of porcine circovirus type 2(PCV2)in some areas of Xinjiang from 2022 to 2023,in order to provide a reference for the scientific prevention and control of the disease.The experiment used the indirect enzyme-linked immunosorbent assay(ELISA)to detect PCV2 antibodies in 296 serum samples from 11 pig farms in three regions.The results showed that the average positive rate of PCV2 antibodies was 85.47%(253/296),higher than the national standard(70%).Among the 11 large-scale pig farms surveyed,except for the farm A and farm C,which did not meet the national standard for PCV2 antibody levels,81.82%(9/11)of the pig farms reached the antibody level and immunization standard for herd immunity.The study indicates that the overall immunization effect of PCV2 in pig farms in the Xinjiang area is good,but some farms have lower levels of PCV2 antibodies,necessitating adjustments and improvements to existing immunization procedures to ensure the health of all pig herds.
