| 目的 了解自1980-2012年在世界各地分离的版纳病毒分子遗传进化特征。方法 采用多种生物信息学分析方法，对1980-2012年我国及世界各地分离的版纳病毒进行基于第12节段基因序列的系统进化、分子溯源分析。结果 版纳病毒的共同进化祖先出现时间为315（95% HPD：63～619）年前，第12节段的进化速率为2.33×10-3（95% HPD：2.84×10-4～8.52×10-3）碱基替换/位点/年，提示版纳病毒属于新发快速进化的虫媒病毒。结论 版纳病毒属于快速进化的新发虫媒病毒，其地域分布范围进一步扩大且已经分化出新的病毒变种，应加强对该病毒在自然界分布及其致病性的监测。 |

| Objective To understand the evolution characteristics of Banna viruses (BAVs) isolated worldwide from 1980 to 2012. Methods In this study, a phylogenetic analysis using Bayesian Markov Chain Monte Carlo simulations was conducted on all available 12th segment of genes of BAVs isolated worldwide from 1980 to 2012 to investigate the evolutionary and epidemiologic dynamics of BAVs. Results The Bayesian phylogenetic analysis of BAVs revealed that the common ancestor of BAVs appeared 315 (95%HPD:63-619) years ago. The evolutionary rate of BAV based on the 12th segment gene was estimated to be 2.33×10-3 (95%HPD:2.84×10-4-8.52×10-3) substitution per site per year, indicating BAV belong to an emerging arbovirus with rapid evolution. Conclusion The evolution of emerging BAVs is rapid and the distribution of BAVs has expanded with new variant being detected, so it is necessary to enhance the surveillance to fully understand the natural distribution and pathogenicity of BAVs. |
