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 or endocarditis.

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 is used to treat VRE infections. The streptogramins, such as quinupristin/dalfopristin, may also be used for VREs. VRE can be successfully treated with sultamicillin.[4]
