摘　　要：为了了解禄丰地区部分猪群中蓝耳病病毒感染情况及疫苗免疫情况,为蓝耳病的防控提供参考,试验用ELISA方法对云南禄丰部分规模猪场进行了猪蓝耳病血清抗体的检测,共检测8个规模化猪场的150份血清。结果显示:8个规模化猪场猪蓝耳病抗体阳性率分别为100%,93.30%,90.00%,82.76%,83.33%,14.70%,9.10%和3.70%;蓝耳病抗体平均值分别是0.117,1.395,1.115,0.036,0.075,0.603,1.286和0.758,离散度分别是0.164,0.566,0.527,0.071,0.061,0.691,0.548,0.577。结果表明不同猪场的猪蓝耳病阳性率及抗体水平存在一定差异,同时调查表明:云南禄丰地区大部分规模猪场的猪群蓝耳病免疫效果合格,同时也存在小部分猪群蓝耳病免疫效果欠佳的情况。To grasp the situations of porcine reproductive and respiratory syndrome （PRRS）virus infection and vaccine vaccination in some pig hends - from the Lufeng area in Yunnan Province, and to provide a reference for the prevention and control of PRRS, an ELISA assay was used to detect the antibody against PRRS in this test. 150 sera were collected from the pigs in 8 large - scale pig farms in Lufeng. The results showed that the positive rates for PRRS antibody in the eight large - scale pig farms were 100%, 93.30% ,90.00%, 82.76%, 83.33%, 14.70%, 9.10%, and 3.70%, respectively; and the average values of antibody against PRRS in the pig farms were 0.117, 1. 395, 1.115, 0. 036, 0. 075, 0.603, 1. 286 and 0. 758, respectively; and the discrete degree were 0. 164,0. 566,0. 527,0. 071,0. 061,0. 691,0. 548 and 0. 577, respectively. The results indicate that there are certain differences in the positive rates for PRRS and levels of antibody against PRRS between different pig farms. At the same time, the results of the survey may suggest that the immune effects of PRRS vaccine against PRRS infection are qualified in the pig herds from a majority of large - scale pig farms, but there are poor immune effects in small parts of pig herds.
