To further understand the emergence of serotype IV group B Streptococcus (GBS) invasive disease, we used whole-genome sequencing to characterize 3 sequence type 468 strains isolated from neonates in Minnesota, USA. We found that strains of tetracycline-resistant sequence type 468 GBS have acquired virulence genes from a putative clonal complex 17 GBS donor by recombination.
为了进一步了解B族链球菌血清型IV(GBS)侵袭性疾病的出现情况,我们使用全基因组测序对从美国明尼苏达州新生儿中分离出的3株序列类型468菌株进行了特征分析。我们发现,耐四环素序列类型468的GBS菌株通过重组从一个假定的克隆复合体17 GBS供体处获得了毒力基因。
