The prevalence of insertion sequences IS1548, IS861, IS1381, and ISSa4 and of the group II intron GBSi1 within Streptococcus agalactiae human isolates strongly correlates with the genetic lineages obtained by multilocus sequence typing. Our results yielded an evolutionary scheme for the acquisition of these genetic elements linked to the ecosystems from which the isolates were obtained.
无乳链球菌人类分离株中插入序列IS1548、IS861、IS1381和ISSa4以及II类内含子GBSi1的流行率与多位点序列分型获得的遗传谱系密切相关。我们的结果产生了一个关于获取这些与分离株来源生态系统相关的遗传元件的进化方案。
