摘　　要：应用PCR技术,结合临床观察、病理解剖对福建省不同地区断乳多系统衰竭综合征(PMWS)发病猪群采集的病料进行多重病原检测与分离。结果表明50份病料中猪圆环病毒2型(PCV2)、猪繁殖与呼吸综合征病毒(PRRSV)、猪瘟病毒(CSFV)、猪伪狂犬病病毒(PRV)阳性率分别为40%、26%、4%、0,不同地区各病原检出率差别不大。病毒性混合感染以PCV2和PRRSV为主,感染率为22%;PCV2与CFSV混合感染率为4%;PRRSV与CFSV混合感染率为4%;PCV2、CFSV、PRRSV三种病原混合感染率为4%。研究结果表明福建大部分地区猪群PMWS的发生是PCV2、PRRSV、CSFV等多种病原混合感染的结果,其主要病原为PCV2,该病的发生没有明显地域性。The study detected various kinds of pathogens in pigs suffering from Post-weaning muhisystemic wasting syndrome by PCR technique, body examination and pathological anatomy. The results showed that the positive rate of PCV2, PRRSV, CSFV and PRV in fifty samples were 40%, 26%, 4% and 0, respectively~ the co-infection rate of PRRSV/PCV2, CSFV/PCV2, PRRSV/CSFV and PCV2/CFSV/PRRSV were detected in 22%, 4%, 4% and 4%, respectively. The data obtained in the present study indicated that the casue of PMWS was the co-infection of PCV2, PRRSV and CSFV, though the major pathogen was PCV2 and no significantly differ- ences were observed in genetic and geographic origin.
