摘要
对采自湖北省内16家规模化养猪场的650份组织样品分别进行猪圆环病毒(Porcine circovirus,PCV)和猪流行性腹泻病毒(Porcine epidemic diarrhea virus,PEDV)的病原学检测。结果表明:除PCV4未检出阳性外,PCV1、PCV2、PCV3、PEDV单一感染的样品阳性率分别为1.08%、4.15%、2.46%和6.46%;在双重感染中,以PEDV+PCV2的阳性率最高,达3.54%,其次为PCV2+PCV3,其阳性率为1.54%;在多重感染中,以PEDV+PCV2+PCV3的阳性率最高,为2.00%。虽然PEDV、PCV感染的阳性率较前期调查结果有所下降,但它们在湖北省内流行仍较广,且以混合感染为主。
In this study,650 tissue samples which were collected from 16 pig farms in Hubei Province,were used to detect porcine circovirus(PCV)and Porcine epidemic diarrhea virus(PEDV).The results showed that the positive rates of PCV1,PCV2,PCV3 and PEDV single infection were 1.08%,4.15%,2.46%and 6.46%,respectively.In the double infections,PEDV+PCV2 had the highest positive rate of 3.54%,followed by PCV2+PCV3,with a positive rate of 1.54%.In multiple infections,PEDV+PCV2+PCV3 had the highest positive rate of 2.00%.The results indicated that the positive rates of PEDV and PCV were decreased compared with the previous studies,but the prevalence of PEDV and PCV was still wide in Hubei Province,and most of which were co-infection.
