福建省猪流行性腹泻流行病学调查

为探求2012-2013年猪流行性腹泻病毒（PEDV）在福建省的流行情况，本研究采用RT-PCR方法对采自福建省125个规模猪场的257份发生腹泻病料进行PED病原检测，并分析PEDV致猪群的发病情况。结果：被检病料PEDV的阳性率为63.04%（162/257），能导致不同阶段猪群发病，尤其是对哺乳仔猪的发病率最严重，死亡率高达100%。表明：PEDV在我省发病仍较为严重，应加强防控，以减少损失。

To investigate porcine epidemic diarrhea virus (PEDV) epidemic situation from 2012 to 2013 in Fujian province, the authors tested 257 diarrhea samples from 125 farms by RT-PCR assay and analyzed PEDV infection in swine herd. The result showed that the positive rate of PEDV was 63.04% (162/257); swine of different ages were all susceptible to PEDV infection, especially piglets, which had 100% mortality rate.
