Genomic analysis of type emm59 group A Streptococcus invasive strains isolated in the United States discovered higher than anticipated genetic heterogeneity among strains and identified a heretofore unrecognized monoclonal cluster of invasive infections in the San Francisco Bay area. Heightened monitoring for a potential shift in the epidemic behavior of emm59 group A Streptococcus is warranted.
对美国分离的emm59 组 A 链球菌侵袭株进行基因组分析发现,菌株间存在高于预期的遗传异质性,并鉴定出旧金山湾区一个以前未被识别的侵袭性感染单克隆群。有必要加强监测,以预防 emm59 组 A 链球菌的流行行为可能发生变化。
