Enterococcus faecium is a Gram-positive, alpha hemolytic or nonhemolytic bacterium in the genus Enterococcus.[1] It can be commensal (innocuous, coexisting organism) in the human intestine, but it may also be pathogenic, causing diseases such as neonatal meningitis.

Vancomycin-resistant E. faecium is often referred to as VRE.[2]

Some strains of E. faecium are used as probiotics in animals.[3]

Treatment[edit]

Linezolid or daptomycin are used to treat VRE infections. The streptogramins, such as quinupristin/dalfopristin, may also be used for vancomycin-resistant E. faecium, but not E. faecalis.Vancomycin resistant E.faecium can be successfully treated with sultamicillin.[4]
