猪传染性胸膜肺炎在保育猪中的流行病学调查

摘要

[Objective]To investigate the infection rates of Actinobacillus pleuropneumoniae on piglets in large and medium scale pig farms. [Method] Total of 272 piglets sera collected from 10 different swine farms were detected for the antibody against APP by using ApxIV-ELISA method. [Result]The re-sults showed that the total positive rates of A.pleuropneumoniae in all detected pig samples were 32.4%. [Conclusion] These results indicated that A.pleurop-neumoniae was very common in part of scale pig farms. The infection rates of A. pleuropneumoniae on piglets in large and medium scale pig farms were high and no obvious regularity. The infection rates of piglets were not related to incidence of disease. The liquidity of the pigs out-side had little effect on the A. pleurop-neumoniae infection rates in farms.%[目的]调查大、中型规模种猪场保育猪胸膜肺炎放射杆菌（APP）感染情况。[方法]用ApxIV-ELISA 试剂盒检测272份保育猪血清。[结果]有88份猪血清样品检测到APP感染抗体阳性，阳性率为32.4%。[结论]APP普遍存在于各猪场，大、中型种猪场保育猪APP 感染抗体阳性率偏高且无明显规律，保育猪APP 的感染率与猪只是否发病无关，场外猪群的流动性对大型猪场内APP的感染率影响不大。
