| 摘 要： | 应用RT-PCR、PCR和细菌分离等方法,对陕西某规模化养猪场发生的仔猪渐进性消瘦、呼吸困难和母猪繁殖障碍为主要特征的疾病进行了流行病学调查和病原分离鉴定。结果表明,该猪场猪繁殖与呼吸综合征病毒(PRRSV)和2型猪圆环病毒(PCV2)感染相当严重,从出现胸肺粘连的病猪实质脏器中可分离到致病性大肠杆菌和沙门氏菌,未分离到胸膜肺炎放线杆菌。该猪场此次疫情主要是由于猪PRRSV、PCV2、大肠杆菌和沙门氏菌四重混合感染而引起。

| Abstract: | A new zootic disease characterized by respiratory disease in young swine,postweaning multisystemic wasting syndrome and reproductive failure of sows occurred at a pig farm in Shaanxi Province.The pathogens were detected and isolated by RT-PCR,PCR and bacteria isolation.The results indicated that the disease was infected seriously with mixinfection of PCV2 and PRRSV;pathogenic E.coli and S.gallinarum were isolated in the substance viscera pigs of conglutination between thorax and lung;A.pleuropneumoniae was not found;the disease was diagnosed as mixinfection of PCV2,PRRSV,E.coli and S.gallinarum by the study of epidemiology,clinicalsigns,typicallesions,and laboratorytests. |
