摘要
运用乳胶凝集试验(LAT)和ELISA方法对酒泉、张掖、金昌、武威、兰州、临夏、白银、定西、天水和平凉10个市州38个规模化和农村个体养猪场送检的619份血样和血清进行了PPV、PR、PRRS和JE免疫抗体检测,3年度平均阳性率PPV为80.83%、PR为60.70%、PRRS为43.39%、JE为47.57%,免疫抗体平均阳性率以PPV最高,PRRS和JE免疫抗体平均阳性率偏低。对8市州24个猪场采送的132份血清进行的PPV、PR、PRRS和JE感染抗体检测表明,PPV感染抗体平均阳性率为18.57%、PR感染抗体平均阳性率为15.28%、PRRS感染抗体平均阳性率为23.28%J、E感染抗体平均阳性率为24.14%。
The 617 sera from 38 swine farms in Jiuquan, Zhangye, Jinchang, Wuwei, Lanzhou, Linxia, Baiyin, Dingix Tianshui and Pingliang 10 cities（states） of Gansu province were examined by LAT and ELISA using the antibodies against 4 diseases, ineluding porcine parvivirus infection （PPV）, pseudorabies（PR）, porcine reproductive and respiratory syndrome（PRRS）and Japanese B encephalitis （JE）. The results showed positive rate of PPV immunity antibody was 80.83%, PR immunity antibody rate was 60.70%, PRRS immunity antibody rate was 43.39%, JE immunity antibody rate was 47.57%. PPV infection antibody rate was 18.57%, PR infection antibody rate was 15.28%, PRRS infection antibody rate was 23.28%, JE infection antibody rate was 24.14%.
