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 both animals,^[3] and humans.^[4]

Treatment

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.^[5]

This study aimed to compare two different approaches for the purification of enterocin B from Enterococcus faecium strain W3 based on the observation that the bacteriocin was found both in cell associated form and in culture supernatant. The first approach employed ammonium sulfate precipitation, ca
