High Prevalence ofvanMin Vancomycin-Resistant Enterococcus faecium Isolates from Shanghai, China

Abstract

ABSTRACTThevanMgene was first found in a vancomycin-resistantEnterococcus faecium(VREm) isolate in Shanghai in 2006. In this study, we found that, in 70 VREm strains isolated in nine Shanghai hospitals from 2006 to 2014,vanMwas more prevalent than thevanAgene (64.3% [45/70] versus 35.7% [25/70]). ThevanM-type isolates showed similar antimicrobial susceptibility patterns with thevanAtypes. ThevanM-type VREm emerged and disseminated in Shanghai.
