中国狂犬病病毒的分群和进化特征

Grouping and evolution characteristics of rabies virus in China

  • 摘要: 目的 为全面掌握我国狂犬病病毒的遗传进化特征和分群特点。 方法 对GenBank上具有明确时间、地域及宿主信息的中国街毒株G基因全序进行汇总,并结合本实验室获得的中国流行株G序列,利用BEAST软件,进行系统的时间进化分析。 结果 中国狂犬病流行株G基因的时间进化分析显示,我国流行株明显分为6群:ChinaⅠ群是我国的绝对优势群,数量占总数的80%以上,分布于19个省(自治区、直辖市);ChinaⅡ群,包括来自7个省(自治区、直辖市)的49个流行株;ChinaⅢ、 Ⅳ、Ⅴ和Ⅵ群数量较少,分布地域也较为局限。中国流行株的最近共同祖先(TMRCA)可追溯至392年前。 结论 ChinaⅠ群是我国目前优势毒株群,同时应注意防范ChinaⅡ群和ChinaⅣ群野生动物来源的狂犬病流行。

     

    Abstract: Objective To fully understand the grouping and evolution characteristics of rabies virus in China. Methods The phylogenetic analysis of rabies virus in China was conducted by using G gene complete sequences of China rabies street strains with clear background information obtained from GenBank and the G gene sequences of China rabies circulating strains collected by our laboratory with BEAST software. Results The analysis indicated that China rabies street strains can be classified as 6 groups:Group China Ⅰ is predominant, accounting for 80%, and circulates in 19 provinces. Group China Ⅱ, including 49 strains, circulates in 7 provinces. Group China Ⅲ, China Ⅳ, China Ⅴ and China Ⅵ include a few strains and circulate in limited areas. It is estimated that TMRCA, the common ancestor of China rabies circulating strains, was detected about 392 years ago. Conclusion Rabies virus group China Ⅰ is predominant in China, but the prevention and control of rabies caused by China Ⅱ and China Ⅵ viruses, related with wild animal rabies, should not be neglected.
