Enterococcus faecalis – formerly classified as part of the group D Streptococcus system – is a Gram-positive, commensal bacterium inhabiting the gastrointestinal tracts of humans. [ 1 ] [ 2 ] Like other species in the genus Enterococcus , E. faecalis is found in healthy humans and can be used as a probiotic.
The combination of daptomycin and ampicillin is another option to treat VRE infections, especially for bacteremia. [19] For invasive vancomycin-resistant E. faecalis infections, both ampicillin-ceftriaxone and ampicillin-gentamicin combinations have been used successfully, with the latter specifically showing success in treating endocarditis.

Enterococcus is a large genus of lactic acid bacteria of the phylum Bacillota. Enterococci are Gram-positive cocci that often occur in pairs ( diplococci ) or short chains, and are difficult to distinguish from streptococci on physical characteristics alone. [ 2 ]
The evolution of bacteria on a "Mega-Plate" petri dish A list of antibiotic resistant bacteria is provided below. These bacteria have shown antibiotic resistance (or antimicrobial resistance). Gram positive Clostridioides difficile Clostridioides difficile is a nosocomial pathogen that causes diarrheal disease worldwide. Diarrhea caused by C. difficile can be life-threatening. Infections are ...
Dalbavancin also shows in vitro activity against vancomycin-susceptible Enterococcus faecium and Enterococcus faecalis. [3] Other Gram-positive organisms belonging to the Bacillus spp., Listeria spp., and Corynebacterium spp. may show in vitro susceptibility, and dalbavancin may exhibit activity against enterococci expressing the VanB or VanC ...
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. [9] [10] Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant Staphylococcus aureus (MRSA).
Tigecycline can treat complicated skin and structure infections caused by; Escherichia coli, vancomycin-susceptible Enterococcus faecalis, methicillin-resistant Staphylococcus aureus, Streptococcus agalactiae, Streptococcus anginosus grp., Streptococcus pyogenes, Enterobacter cloacae, Klebsiella pneumoniae, and Bacteroides fragilis. [11]
Antibiotics with less reliable but occasional (depending on isolate and subspecies) activity: occasionally penicillins including penicillin, ampicillin and ampicillin-sulbactam, amoxicillin and amoxicillin-clavulnate, and piperacillin-tazobactam (not all vancomycin-resistant Enterococcus isolates are resistant to penicillin and ampicillin)
