A phylogenetic approach was used to identify genetic variants of DENV-3 subtype III that may have emerged during or after its expansion throughout South America. We sequenced the capsid, premembrane/membrane and envelope genes from 22 DENV-3 strains isolated from Venezuela, Bolivia, Ecuador and Peru between 2000 and 2005. Phylogenetic analysis showed that the isolates sequenced in this study formed three clades within subtype III: one with the isolates from Venezuela, one with the Bolivian isolates and one with the isolates from Ecuador and Peru.
采用系统发育方法来鉴定登革热病毒3型(DENV-3)III亚型在整个南美洲传播期间或之后可能出现的基因变异。我们对2000年至2005年间从委内瑞拉、玻利维亚、厄瓜多尔和秘鲁分离出的22株DENV-3病毒株的衣壳、前膜/膜和包膜基因进行了测序。系统发育分析表明,本研究中测序的分离株在III亚型内形成了三个分支:一个分支包含来自委内瑞拉的分离株,一个分支包含来自玻利维亚的分离株,另一个分支包含来自厄瓜多尔和秘鲁的分离株。
