摘要
采用PCR方法对上海及周边地区散养临床发病猪进行主要病毒病的病原学检测,主要包括猪瘟病毒、猪繁殖与呼吸综合征病毒、猪伪狂犬病病毒和猪圆环病毒2型。2005年检测病死猪病料97份,4种病的阳性率分别为33.33%、23.81%、35.90%、40.00%;2006年检测357份,4种病的阳性率分别为15.91%、33.33%、10.53%、23.61%;2007年检测1050份,4种病的阳性率分别为13.92%、35.20%、7.78%、20.57%。2005年-2007年的病例中均有不同程度的混合感染,混合感染率分别为3.09%、4.48%、3.62%,表明这些病原在上海及周边地区的散养猪中普遍存在,成为猪病防疫中不可忽视的一个环节。
The pathogens of main swine virus disease in small-scale pig farms in Shanghai and peripheral areas were detected by using PCR method. These pathogens included HCV,PRRSV,PRV and PCV-2. 97 samples were detected in 2005 ,four disease positive rates were 33.33% ,23.81% ,35.90% ,40.00%, respectively; 357 samples were detected in 2006, the positive rates were 15. 91% ,33.33%, 10.53% ,23.61% ,respectively;1 050 samples were detected in 2007, the positive rates were 13. 92%, 35. 20%, 7. 78%, 20.57 %, respectively. There were different degree of mixed infections from 2005 to 2007, the mixed infection rates were 3.09%, 4. 48%, 3.62%, respectively. The results showed that these pathogens existed in small-scale pig farms in Shanghai and peripheral areas,and these pathogens were very impotant in controling porcine viral disease.
