摘要:

为探索使用高通量测序测定和分析禽流感病毒全基因的方法,使用Ion Torrent PGM测序仪对20株自华东地区分离的禽流感病毒进行全基因测序,分析该方法的优缺点,以及此20株病毒的基因组特性和进化特征。结果显示,应用Ion Torrent PGM测序仪能够测出全部20株病毒的全基因,确定其均为H9亚型h9.4.2.5分支的低致病性毒株,NA基因均为N2亚型,并分析了其6个内部基因分子演化关系。说明高通量测序可用于禽流感病毒全基因分析。

Abstract:

To discuss the sequencing and analysis of avian influenza virus (AIV) genome by high-throughput sequencing,genomes of the 20 AIV strains isolated from eastern China were sequenced by Ion Torrent PGM.The advantage and disadvantage of the method were evaluated.The characteristic of genome and evolution were analyzed.The molecular evolution relationships of the other 6 internal genes were also analyzed.The results showed that the whole genomes of all the 20 strains were completely sequenced by Ion Torrent PGM.All the 20 viruses are restricted to h9.4.2.5 clade of H9 subtype low pathogenic strains.NA genes of all the viruses are N2 subtype.High-throughput sequencing can be used in the genome analysis of AIV strains.
