猪圆环病毒2型和猪瘟病毒抗体检测与分析

Detection and Analysis of Porcine Circovirus 2 and Classical Swine Fever Virus Antibodies

目的检测临汾市某县猪圆环病毒2型(PCV2)和猪瘟病毒(CSFV)的抗体水平。方法分别从该县的企业、散户、大户的猪只中采集血清186份,应用ELISA方法检测抗体水平。结果 PCV2抗体阳性率平均为83.33%,CSFV抗体阳性率平均为54.83%。结论该县猪圆环病毒2型感染严重,猪瘟疫苗免疫抗体水平偏低,与猪瘟疫苗使用不当、猪圆环病毒2型感染存在一定关系。

Objective To monitor the antibody level of porcine circovirus 2 （PCV2） and classical swine fever virus（CSFV） in Linfen. Method 186 swine serum samples were collected separately from the enterprises, retails, large-scale farmers, and tested for the antibody level with ELISA. Results The average positive rate of PCV2 was 83.33%, while that of CSFV was 54.83%. Conclusion The infection of PCV2 was serious; the immune antibody level of CSFV vaccine was relatively low, this maybe related with misuse of CSFV vaccine and the PCV2 infection.
