摘　　要：对甘肃省内规模和散养临床发病猪病料,采用PCR和细菌分离鉴定方法进行CSFV、PR、PRRS和PCV-2四种主要病毒病病原学检测和PCP放线杆菌分离鉴定。5年共检测病死猪病料1213份,CSF、PCV-2、PRRS、PR、PCP的平均阳性率分别为42.8%、34.3%、31.8%、30.2%、33.5%;5年共检测养殖场/户326个,5种病的检出率分别为62.6%、15.3%、14.7%、18.4%、21.5%。养殖场/户猪群疫病的感染以混合感染为主,混合感染占检测病例总数的62.6%,五种病混合感染分别占各自感染例数的为54.9%、92.0%、75.0%、80.0%、82.9%。其中二重感染占80.4%。形式以CSF+PCP、CSF+PR、CSF+PRRS和PCV-2+PRRS居多,CSF单独感染占所有单独感染病例的75.4%。An experiment has been done from 2005 to 2009 to study swine diseases which included both big size pig farms and scatter wild pigs in Gansu province.This experiment studied CSF,PR,PRRS,PCV and PCP by Reverse-transcription polymerase chain reaction（RT-PCR） and bacteria separation identification technology.During 5 years,1213 dead pigs have been detected.The results showed that the positive rate of CSF,PCV,PRRS,PR,PCP was 42.8%,34.3%,31.8%,30.2% and 33.5%,respectively.And during 5 years,326 farms and farmers were also studied.The tested positive of that 5 diseases was 62.6%,15.3%,14.7%,18.4% and 21.5%,respectively.Most of these infections were co-infection,which accounted for 62.6% among total detected pigs.Co-infection cases possessed 54.9%,92.0%,75.0%,80.0% and 82.9%.Among them,double infection possessed 80.4%.The infectious form was CSF＋PCP,CSF＋PR,CSF＋PRRS and PCV-2＋PRRS,CSF single infection possessed 75.4% of all single infection cases.
