摘要: 2014年2月,突遇降雪天气,某规模化猪场2 000头母猪中约100头母猪所产新生仔猪集中在1周龄内出现大批死亡现象,死亡前均出现呕吐、消瘦及水样稀粪症状。通过采用现场调查、实验室病理解剖、病理组织学观察、免疫组化、RT-PCR、测序、ELISA检测等方法,本试验确定该病是猪流行性腹泻病毒(PEDV)变异野毒株感染引起,同时混合感染猪圆环病毒2型(PCV2)。通过采取母猪群紧急接种疫苗、仔猪口服卵黄抗体及加强保温、消毒等综合措施,该病迅速得到控制。

Abstract: In February 2014,piglets of a certain 100 sows,fed in a large-scale pig farm which had 2 000 sows,died acutely and densely in one week with vomit,emaciation and lethal watery diarrhea after sudden snowy weather.By field survey,pathological anatomy,histopathological observation,immunohistochemistry,reverse transcription-polymerase chain reaction (RT-PCR),sequencing and enzyme-linked immune sorbent assay (ELISA),porcine epidemic diarrhea virus (PEDV),co-infecting with porcine circovirus 2 (PCV2),was confirmed to be the major agent.By adopting measures,including emergency vaccination of sows,egg yolk antibody oral inoculation of piglets,and insulation and disinfection,the disease was successfully and speedily controlled.

Key words: porcine epidemic diarrhea virus; RT-PCR; S gene; diagnose
