Enterococcus faecalis strain VV5

Enterococcus faecalis strain VV5 is a Gram-positive cocci bacterium characterized as a chemoorganotroph and facultative anaerobe. It thrives optimally at 37°C and is classified as mesophilic. This strain has a single membrane and a single replicon, indicating a simpler genomic structure. Notably, it lacks mobility, as it does not possess flagella. E. faecalis strain VV5 is free-living and can inhabit multiple environments. Its biotic relationships extend to a variety of hosts, including Homo sapiens, Gallus gallus, Bos species, various Metazoa, Lutjanus russellii, Danio rerio, Sus scrofa, Insecta, Canis lupus familiaris, Felis catus, and Phocoena phocoena. This diverse host range highlights its ecological versatility and potential for transmission across species. This strain is associated with numerous health effects, primarily in humans, where it can cause serious infections such as bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and septicemia. It is also implicated in nosocomial infections and can affect various body parts, including the urinary tract, intra-abdomen, and oral cavity. The ability of E. faecalis to cause infections in both healthy and compromised hosts underscores its pathogenic potential. The prevalence of E. faecalis in clinical settings, coupled with its capacity to inhabit multiple hosts, emphasizes its importance in both human health and the broader ecological context. This adaptability may contribute to its role in infections, particularly in nosocomial environments where antibiotic resistance is a growing concern.
