猪圆环病毒2型和猪繁殖与呼吸综合征病毒混合感染的流行病学调查
Investigation on Epidemiology of Co-infection of Porcine Reproductive and Respiratory Syndrome Virus and Porcine Circovirus Type 2
摘要
Abstract
The research was to study the epidemiology of co-infection of porcine circovirus type 2 and Porcine reproductive and respiratory syndrome virus in parts of China during 2009 -2010. A total of 227 tissue and serum samples of diseased pigs obtained from Jiangsu,Anhui,Shanghai,Shandong,Zhejiang,Fujian and Jiangxi provinces of China during 2009 -2010 were detected for PCV2 and PRRSV by PCR or RT-PCR. The results showed that the positive rate of PCV2a,PCV2b and PRRSV were 15.9% ,44. 5% and 45. 8% respectively. 17 samples were positive for PCV2a and PRRSV,50 samples were positive for PCV2b and PRRSV, 10 samples were positive for PCV2a, PCV2b and PRRSV,and the corresponding co-infection rate were 7.5% ,22.0% and 4.4% respectively. All these results indicated that the PCV2 and PRRSV infection were widespread and co-infection of PCV2 and PRRSV was prevalent in parts of China during 2009 -2010. The high co-infection rate also increased the difficulty of prevention and controlling diseases of swine.关键词
