摘　　要：【目的】研究2012年我国部分地区猪圆环病毒2型(PCV2)、类猪圆环病毒P1和猪输血传播病毒(TTV)混合感染的情况。【方法】采用PCR方法对采集自我国江苏、安徽和浙江3省的108份组织和血清样品进行PCV2、P1和TTV检测。【结果】PCV2感染率为64.81%,P1感染率为12.96%,TTV1感染率为33.33%,TTV2感染率为51.85%,其中8份样品表现为PCV2和P1的混合感染,42份样品表现为PCV2和TTV的混合感染,4份样品表现为PCV2、P1和TTV的混合感染,分别占样品总数的7.41%、38.89%和3.7%。【结论】猪群中PCV2和TTV的感染比较普遍,P1的感染率较低,PCV2和TTV的混合感染率较高,混合感染种类复杂,加重了疫病防控的难度。To study the epidemiology of co-infection of porcine circovirus type 2 （PCV2） ,porcine circovirus-like agent P1 （P1） and Torque Teno virus （TTV ） in China , 2012 ,108 tissue and serum samples of diseased pigs obtained from Jiangsu ,Anhui and Zhejiang provinces of China were detected for PCV 2 ,P1 and TTV by PCR . The results showed that the positive rate of PCV2 ,P1 and TTV were 12.96% ,33.33% and 51.85% respectively .8 samples were positive for both PCV2 and P1 ,42 samples were positive for PCV2 and TTV as well ,4 samples were positive for all of the three ,and the corresponding co-infection rate were 7.41% ,38.89% and 3.7% respectively . These results indicated that the PCV2 and TTV infection were widespread ,while the prevalence of P1 infection was lower . The co-infection of different viruses was complicated and the PCV 2-TTV co-infection rate was the highest , which increased the difficulty of prevention and controlling diseases of swine .
