| 摘 要： | 根据GenBank_h发表的猪圆环病毒2型（Porcinecircovirustype2，PCV2）基因组序列和TTV（Torquetenovirus）1、2型的UTR序列设计合成引物，建立了分别用于检测PCV2和TTV1、TTV2的PCR及巢式PCR方法。应用建立的PCR方法对送检的广东、福建和江西等7个省份258份血液和组织样品进行了PCV2、TTV1和TTV2的检测，确定猪群中PCV2与TTV1和／或TTV2混合感染情况。结果表明，94份样品表现为PCV2和TTV1的混合感染，占样品总数的36．4％；193份样品表现为PCV2和TTV2的混合感染，占74．8％；另外，还有一些样品为三重感染，占34．5％。由此可以看出，猪群中PCV2和／或TTV1和／或TTV2的混合感染很普遍。

| Abstract: | According to the published genomic sequences of Porcine circovirus type 2(PCV2) and the UTR sequence of swine Torque teno virus(TTV),primers were designed and a PCR and nest PCR were set up for the detection of PCV2 and TTV,respectively.258 blood and swine tissue samples collected from fields were detected for PCV2 and TTV by PCR.The results demonstrated that the co-infection rate of PCV2+TTV 1,PCV2+TTV2 or PCV2+TTV 1 +TTV2 were 36.4%,74.8%and 34.5%,respectively.The data obtained in the present study indica... |
