海南省规模猪场猪传染性胸膜肺炎的血清学调查

Serological Investigation on Porcine Contagious Pleuropneumonia in Scale Pig Farms of Hainan Province

为了解海南省规模猪场猪传染性胸膜肺炎(PCP)的感染情况,采集海南省8个市县16个不同规模猪场血清样品1 286份,用ELISA方法对猪胸膜肺炎放线杆菌(APP)ApxⅣ抗体进行检测,分析APP的感染情况。结果显示,1 286份猪血清样品共检出阳性样品436份,抗体阳性率为33.90%。其中,检测母猪血清326份,抗体阳性率为47.85%;检测哺乳仔猪血清324份,抗体阳性率为37.65%;检测保育猪血清316份,抗体阳性率为18.99%;检测育肥猪血清320份,抗体阳性率为30.63%。8个市县均有APP感染,其中文昌市APP抗体阳性率最高;不同规模猪场均有APP感染,其中中型规模猪场APP抗体阳性率最高;不同品种猪均有APP感染,其中杜长陆三元杂猪APP抗体阳性率最高。说明PCP在海南省部分规模猪场中普遍存在,对猪场进行PCP的控制是十分必要的。

In order to understand the infection of porcine contagious pleuropneumonia（PCP）in scale pig farms of Hainan province,1 286 pig sera collected in 16 different scaled pig farms in Hainan province were tested with Actinobacillus pleuropneumoniae（APP）ApxⅣantibody detection kit.The results showed the total positive rates were 33.90%（436/1286）,among which the positive rate was 47.85%（156/326）in sows,37.65%（122/324）in sucking pigs,18.99%（60/316）in weaned pigs and 30.63%（98/320）in fattening pigs.Wenchang city got the highest positive rate,and middle-scaled pig farms got higher positive rate too.All the breeds were infected with APP,the DLL hybrid pigs got the highest positive rate.The above results indicated that the porcine contagious pleuropneumonia occurred in part scale pig farms of Hainan and the PCP control is necessary.
