Molecular epidemiological analysis of Enterococci. Enterococcus faecium

To characterize Japanese enterococcal isolates carrying linear plasmids, whole-genome sequencing was performed. All strains analyzed were clinical strains detected at medical institutions in Japan from 2000 to 2019. Of the 16 strains analyzed in this study, 13 were vancomycin-resistant enterococci and 3 were vancomycin-susceptible, and all of them were E. faecium.

为对携带线型质粒（linear plasmids）的日本肠球菌分离株进行特征鉴定，本研究开展了全基因组测序（whole-genome sequencing）。本研究所分析的全部菌株，均为2000年至2019年间于日本各医疗机构检出的临床分离株。本次研究纳入分析的16株菌株中，13株为耐万古霉素肠球菌（vancomycin-resistant enterococci），3株为万古霉素敏感株，且所有菌株均为屎肠球菌（E. faecium）。
