Antimicrobial-Resistant Evolution and Global Spread of Enterococcus faecium Clonal Complex (CC) 17: Progressive Change from Gut Colonization to Hospital-Adapted Pathogen

Abstract excerpt

For a long time, Enterococcus faecium (E. faecium) was thought to be a commensal strain in human and animal digestive tracts. However, over the past three decades, some unique E. faecium clones rapidly acquired multiple antimicrobial resistance (AMR), which led these clones to survive hospital environments and become a hospital-adapted E. faecium clonal complex (CC) 17. Since the adaptation of these clones to...
