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 multisystemic 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.
