| 摘 要： | 为分析我国猪细环病毒(TTSuV)和猪圆环病毒2型(PCV2)的共感染情况,利用所设计的TTSuV(TTSuV1、TTSuV2)和PCV2特异性引物对我国29个省市采集的猪群血清样品同时进行PCV2和TTSuV(TTSuV1、TTSuV2) PCR检测,分析混合感染情况.结果所检测的1898份样品中,TTSuV阳性为1103份(58％),PCV2阳性为435份(23％).阳性样品中呈混合感染的有275份(14％),其中TTSuV1和PCV2为249份(13％),TTSuV2和PCV2为200份(10％),均为阳性的有174份(9％).调查结果显示,我国猪群中TTSuV和PCV2混合感染现象较为普遍,对地区性分布特征和饲养模式等影响因素的分析表明TTSuV和PCV2混合感染情况存在地区性差异(P＜0.01),但饲养模式并不是共感染的关键因素.

| Abstract: | The aim of this study was to investigate the prevalence of porcine circovirus 2(PCV2) and Torque teno sus virus(TTSuV) co-infection in China,1898 swine serum samples were collected from 29 provinces in China in 2009 and detected for TTSuV1,TTSuV2 and PCV2 by PCR.1 103 samples were TTSuV positive(58%),435 samples were PCV2 positive(23%).Among the positive samples,275(14%) samples were both positive for PCV2 and TTSuV,including 249(13%) infected with both TTSuV1 and PCV2,200(10%) infected with both TTSuV2 and PCV2,and 174 were triple infection.These results suggested that co-infection of TTSuV and PCV2 was highly prevalent in China.Distribution analyses of positive pig herds demonstrated that there were significant difference in different regions,and the breed pattern might not be a factor of aggravation in the co-infection. |
