摘要
为摸清河北省猪群腹泻病的流行情况,2010—2013年,课题组对河北省11个地市的1295个规模猪场进行了腹泻病的流行病学调查,并对114个发病猪群的肠道或粪便样品进行了猪流行性腹泻病毒(PEDV)、猪传染性胃肠炎病毒(TGEV)、猪瘟病毒(CSFV)、圆环病毒2型(PCV-2)、伪狂犬病毒(PRV)和蓝耳病病毒(PRRSV)的检测。结果表明,2010—2013年,河北省猪场腹泻病的发病率分别为29.19%、52.82%、63.04%和33.53%,发病猪群主要以仔猪为主,其发病率和病死率分别为16.19%和72.03%,空间分布显示腹泻疫情从河北南部开始发生,逐渐向北部地区扩散,最后全省趋于平稳。样品中PEDV、TGEV、CSFV、PCV-2和PRV的检出率分别为68.42%、10.53%、13.16%、21.05%和21.93%。
To acquire the distribution of pig diarrhea in Hebei province during 2011-2013, a series of epidemiologi- cal surveys were performed in 1295 pig farms. Some diarrhea samples of feces or intestine contents were collected and detected for porcine epidemic diarrhea virus （PEDV） , transmissible gastroenteritis virus （TGEV） , classical fever swine virus （CSFV） , porcine circovirus 2 （PCV-2） and pseudorabies virus （PRV） and porcine reproductive and respiratory syndrome virus （PRRSV） . The results showed that the total farm positive ratio of diarrhea were 29.19%, 52.82%, 63.04%, 33.53% and 49.58% respectively during 2010-2013, dominantly distributed in the piglets with a high morbidity of 16.19% and case fatality of 72.03%. Spatial distribution revealed that the high incidence rate firstly occurred in the south areas of Hebei province, then spread to the north areas and kept stable across the whole province. The positive rate ofPEDV, TGEV, CSFV, PCV-2 and PRRSV were 68.42%, 10.53%, 13.16 %, 21.05% and 21.93% respectively.
