摘　　要：为摸清贵州地区猪场猪传染性胸膜肺炎及其他疫病感染情况,对来自全省9个地区251个猪场的2 635份血清进行APP、PRRS、CSF、PRV、PCV-2、PPV、JEV、TOX、Mhyo、TGEV、PRCV等11种疫病的血清学检测。结果表明,共有198个猪场的974份血清出现APP抗体阳性,猪场阳性率为78.88%,血清阳性率为36.96%。对APP抗体阳性的198个猪场进行其他疫病检测,发现所有猪场均存在与其他疫病不同程度的混合感染,其中3种混合感染类型(APP/PRV/PCV-2/PPV/JEV/TOX/Mhyo、APP/PRV/PCV-2/PPV/JEV/TOX、APP/PCV-2/PPV/JEV/TOX)较为严重,猪场混合感染率分别为23.74%、17.68%和12.12%;974份APP阳性血清中有968份血清发生APP与其他疫病不同程度的混合感染,混合感染率为99.38%,其中4种混合感染类型(APP/PCV-2/PPV/JEV/TOX、APP/PRV/PCV-2/PPV/JEV/TOX/Mhyo、APP/PRV/PCV-2PPVJEVTOX、APP/PPV/JEV/TOX)较为严重,血清混合感染率分别为12.22%、11.91%、9.24%和8.32%。In order to find out APP and other epidemics mixed infection of scale piggery,2 635 serum samples from 251 herbs of nine districts in Guizhou were tested for APP,PRRS,CSF,PRV,PCV-2,PPV,JEV,Mhyo TGEV TOX,PRCV et al.by serological methods.The results showed that 974 serum samples from 198 herbs were APP positive by ELISA,and the positive rate of farms was 78.88%,the serum positive rate was 36.96%.Moreover,all the 198 herbs in which APP was positive mixed infection with other epidemics.Three kind of mixed infection types（APP、PRV、PCV-2、PPV、JEV、TOX、Mhyo;APP、PRV、PCV-2、PPV、JEV、TOX;APP、PCV-2、PPV、JEV、TOX） were more common that the rate reached to 23.74%、17.68% and 12.12% respectively;968/974 APP positive serum occurred mixed infection with other epidemics.
