    中国病毒学000311摘要:根据猪繁殖与呼吸综合征病毒(PRRSV)美洲型膜蛋白和核衣壳蛋白基因序列,设计了一对含有EcoR I和BamH I酶切位点的引物,用RT-PCR对四个流产猪场的病料进行了检测,扩增出约918 bp的基因片段。通过病毒分离、酶切鉴定和序列分析证实为PRRSV感染。结果说明应用所设计的引物进行RT-PCR快速检测PRRS是可行的,为我国快速特异诊断PRRS和PRRSV强毒株的深入研究奠定了基础。

    Abstract: Primers for RT-PCR were designed on the basis of the M and N gene sequences of U. S. isolate of PRRSV. The primers have restriction endonuclease (EcoR I and BamH I) sites. The tissues of stillborn fetuses of affected swine were detected by RT-PCR in 4 pig farms. The samples were RT-PCR positive. A gene fragment about 918 bp was amplified by RT-PCR, PRRSV were isolated from the tissues of stillborn fetuses. The result showed that PRRSV can be quickly diagnosed by RT-PCR, which laid a basis for quick diagnosis of PRRS and further research of the PRRSV isolates of our country.
