摘要 本试验旨在建立一种同时快速检测鸭坦布苏病毒(DTMUV)和所有亚型禽流感病毒(AIV),且可同时进行H9亚型AIV分型检测的多重PCR检测方法。针对Gen Bank中DTMUV NS2基因、所有亚型AIV的M基因和H9亚型AIV的HA基因的保守序列,分别设计了3对特异性引物,建立了DTMUV和AIV多重PCR检测方法。该方法对混有H9亚型AIV和DTMUV的模板进行PCR扩增,得到了3个大小与试验设计相符的特异性扩增条带,对其他鸭病病原体进行PCR扩增,结果均为阴性。敏感性测定结果表明,该方法能检测到45 pg的DTMUV、7.6 pg的H9亚型AIV和76 pg的M基因。研究建立的多重PCR检测方法,具有快速、敏感、特异等优点,适用于临床检测的应用。
