Enterococcus faecium is a Gram-positive sphereically-shaped (coccus) bacteria that tends to occur in pairs or chains, most commonly involved in HAI in immunocompromised patients. It often exhibits a resistance to β-lactam antibiotics including penicillin and other last resort antibiotics.[1] There has also been a rise in vancomycin resistant enterococci (VRE) strains, including an increase in E. faecium resistance to vancomycin, particularly vancomycin-A.[13] These vancomycin-resistant strains display a profound ability to develop and share their resistance through horizontal gene transfer, as well as code for virulence factors that control phenotypes.
