摘要
目前,已知感染猪群的冠状病毒有6种,分别是猪流行性腹泻病毒(PEDV)、猪传染性胃肠炎病毒(TGEV)、猪呼吸道冠状病毒(PRCV)、猪急性腹泻综合征冠状病毒(SADS-CoV)、猪血凝性脑脊髓炎病毒(PHEV)和猪δ冠状病毒(PDCoV)。在冠状病毒科α、β、γ、δ等4个属中,PEDV、TGEV、PRCV、SADS-CoV均为α冠状病毒,PHEV为β冠状病毒,PDCoV为δ冠状病毒。PRCV在临床上引发仔猪呼吸道症状,PHEV感染会造成仔猪呕吐和神经症状,其他4种病毒均可引起猪群腹泻。
Currently,there are six kinds of coronaviruses known to infect pigs,namely porcine epidemic diarrhea virus(PEDV),transmissible gastroenteritis virus(TGEV),porcine respiratory coronavirus(PRCV),swine acute diarrhoea syndrome coronavirus(SADS-CoV),porcine hemagglutinating encephalomyelitis virus(PHEV),porcine deltacoronavirus(PDCoV).Among the four genera of the family Coronaviridae,PEDV,TGEV,PRCV and SADS-CoV belong to Alphacoronavirus,PHEV belongs to Betacoronavirus,PDCoV belongs to Deltacoronavirus.Clinically,PRCV causes respiratory symptoms in piglets,PHEV leads to vomit and neurological symptoms in piglets,while the other four kinds of viruses cause diarrhea in swine.
