摘要: 根据基因库中新城疫病毒(Newcastle diseases virus,NDV)和鸭瘟病毒(duck plague virus,DPV)的基因序列,分别设计了2对针对NDV和DPV保守基因序列的引物。用这2对引物对同一样品中的NDV和DPV模板进行二重PCR扩增,结果同时得到了2条特异性的、大小与试验设计相符的419(NDV)和602 bp(DPV)的扩增条带,而对其他禽病病原的PCR扩增结果均为阴性。敏感性测定结果表明,该二重PCR技术能同时检出0.4 pg的NDV模板和126 pg的DPV模板。

Abstract: Two sets of specific primers were designed according to the sequences of Newcastle diseases virus (NDV) and duck plague virus (DPV) in GenBank. It was shown that all samples containg NDV and DPV could be amplified into two specific bands, 419 bp for NDV and 602 bp for DPV by this duplex PCR, but no specific band was amplified from other avian pathogenic virus and bacteria. As little as 0.4 pg of NDV RNA and 126 pg of DPV DNA could be detected by this duplex PCR.

Key words: Newcastle diseases virus; duck plague virus; duplex PCR
