文摘为建立H9N2亚型禽流感病毒三重RT-PCR诊断技术,参考Gen Bank登录的H9N2亚型禽流感病毒(AIV)的HA、NA、M基因序列,利用Primer Premier5.0软件设计3对可扩增HA、NA、M基因的特异性引物以及反转录引物。3对引物扩增的c DNA片段大小分别为1 742、1 410、1 027 bp。结果:通过对多重RT-PCR扩增条件的优化,建立了H9N2亚型禽流感病毒三重RT-PCR诊断技术,与目的片段大小相符的片段,经测序均正确,且与其他常见禽病病原不存在交叉反应。该方法对HA基因的最低检出量为10-2μg/μL c DNA,对NA基因的最低检出量为10-2μg/μL c DNA,对M基因的最低检出量为10-3μg/μL c DNA。通过对30份H9N2阳性病毒液进行三重PCR,均可同时扩出HA、NA、M基因。结果表明,本试验建立了H9N2亚型禽流感病毒三重RT-PCR诊断技术,为提高H9N2亚型禽流感病毒HA、NA、M基因序列分析的效率奠定基础。
