摘要: 本试验旨在建立一种能同时快速检测H9亚型禽流感病毒(avian influenza virus,AIV)和鸭坦布苏病毒(duck Tembusu virus,DTMUV)的二重PCR检测方法。根据GenBank中H9亚型 AIV的HA基因和DTMUV的NS2基因序列,分别设计了1对针对H9亚型AIV和DTMUV保守基因序列的引物。利用这2对引物对混有H9亚型AIV和DTMUV的cDNA模板进行二重PCR扩增,得到了2个大小与试验设计相符的特异性扩增条带。利用本试验建立的二重PCR对其他鸭病病原体进行PCR扩增,结果均为阴性。利用这2对引物对H9亚型AIV和DTMUV进行敏感性检测,结果显示最低检测极限分别为6.3和 6.6 pg。对临床235份样品检测的结果表明该二重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。

Abstract: The assay was aimed to establish a duplex PCR assay to detect H9 subtype avian influenza virus (AIV) and duck Tembusu virus (DTMUV) rapidly and simultaneously. According to the sequences of H9 AIV HA gene and DTMUV NS2 gene in GenBank,two sets of specific primers were designed. It was shown that all samples containing H9 subtype AIV and DTMUV could be amplified into two specific bands,but no specific bands were amplified from other duck disease virus. The sensitive determination result indicated that as little as 6.3 pg of H9 subtype AIV and 6.6 pg of DTMUV could be detected by this duplex PCR.Finally,based on 235 samples of clinical test indicated that this duplex PCR assay with the advantages of quick,sensitive and specific,could be useful for the clinical detection.
