摘要
为了解四川地区由胸膜肺炎放线杆菌(APP)引起的猪传染性胸膜肺炎(PCP)的流行情况,本研究利用商品化的ApxⅣ-ELISA试剂盒对来自16个市(区)的552份血清样品进行APP抗体检测。检测结果显示:被检样品的抗体阳性检出率为20.29%(112/552);按地区进行分析,成都地区的阳性率高达42.98%;其中被检种母猪阳性检出率最高,为44.83%(78/174),被检育肥猪阳性检出率最低,为3.95%(3/76);并且冬季的阳性检出率最高,为29.81%(62/208)。该调查结果表明:PCP在四川部分区域存在流行且具有明显的地域性(p<0.05);在不同猪群感染中具有统计学意义(p<0.001),并且与季节有关。本研究覆盖四川主要养猪地区的血清学流行病学调查,为四川地区PCP的预警监测提供实验依据。
To investigate the prevalence of porcine contagious pleuropneumonia （PCP） caused by Actinobacillus pleuropn- eumoniae （APP） in Sichuan area, a total of 552 pig sera collected from 16 different regions were detected for the antibody against APP by the Apx IV-ELISA method. The result showed that the total positive rate was 20.29% （112/552）, of which the 42.98% （49/114） positive rate in Chengdu region was higher than that in other regions, In addition, the positive ratio was the highest in sow with 44.83% （78/174） and the lowest in fattening pigs with 3.95% （3/76）. According to the sampling seasons, 29.81% （62/208） positive was detected in winter, which was highest than in other seasons. These results indicated that the PCP was obviously related with regional characteristics （p〈0.05） in Sichuan. The APP infection shown statistical significance in different pig age （p〈0.001）, but had no obvious difference with the seasons. The epidemiological survey on PCP provided a basis data for prevention of PCP in Sichuan.
