摘要: 为建立快速、准确检测H1亚型禽流感病毒(avian influenza virus,AIV)的方法,本研究针对H1亚型AIV血凝素(HA)基因保守区设计合成了2对特异性引物并优化反应条件进行巢式PCR反应。特异性和敏感性试验结果表明,该PCR方法能特异性检测到H1亚型AIV,其敏感性最低能检测到13.2 fg/μL的H1亚型AIV RNA模板。本研究建立的巢式PCR方法为H1亚型AIV的早期诊断及有效防制提供了快速、特异且敏感的检测方法。

Abstract: In order to develop a simple and quick method to detect H1 subtype avian influenza virus (AIV),two pairs of primers were designed according to the sequences of HA gene of H1 subtype AIV, and a nested polymerase chain reaction (nPCR) method was developed for detection of H1 subtype AIV. The specificity and sensitivity test showed that this nPCR was only specific to the H1 subtype AIV and could detect 13.2 fg/μL of AIV RNA. The results demonstrated that the optimized nPCR assay was rapid, specific and sensitive for detection of H1 subtype AIV.

Key words: H1 subtype avian influenza virus; nested PCR; detection
