Enterococcus faecium is a Gram-positive, alpha-hemolytic or nonhemolytic bacterium in the genus Enterococcus. 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.[Some strains of E. faecium are used as probiotics in both animals, and humans. A probiotic that contains Enterococcus faecium (SF68 strain) has been proposed elsewhere to be clinically effective in the prevention of antibiotic-associated diarrhea and in the treatment of diarrhea in children . However, in another study, no antidiarrheal property of E. faecium (SF68) was found. E. faecium is a human pathogen that causes nosocomial bacteremia, surgical wound infection, endocarditis, and urinary tract infections.
This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
|COGEM released a comprehensive database of pathogenicity assessment of around 2575 bacterial species in 2011. The database ranks the pathogenicity of species on a scale of 1 to 4. Enterococcus faecium ranks 2 on this scale: Species that can cause diseases in humans or animals, which are
unlikely to spread in the human population and for which an adequate
prophylaxis or therapy exists|
