摘要
研究2009-2010年我国部分地区猪圆环病毒2型(PCV2)和猪繁殖与呼吸综合征病毒(PRRSV)混合感染的情况。采用PCR和RT-PCR方法对采集自我国安徽、江苏、山东、浙江等7省的227份组织和血清样品进行PCV2和PRRSV检测。PCV2a感染率为15.9%,PCV2b感染率为44.5%,PRRSV感染率为45.8%,其中17份样品表现为PCV2a和PRRSV的混合感染,50份样品表现为PCV2b和PRRSV的混合感染,10份样品表现为PCV2a,PCV2b和PRRSV的混合感染,分别占样品总数的7.5%,22.0%和4.4%。猪群中PCV2和PRRSV的感染比较普遍,混合感染率也较高,加重了疫病防控的难度。
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.
