Enterococcus faecalis strain VV8

Enterococcus faecalis strain VV8 is a Gram-positive bacterium characterized by its cocci shape and non-motility, lacking flagella. This strain is categorized as a facultative anaerobe, allowing it to thrive in both oxygen-rich and oxygen-poor environments. It is a chemoorganotroph, utilizing organic compounds as its energy source, and has an optimal growth temperature of 37°C, placing it within the mesophilic temperature range. E. faecalis strain VV8 is free-living, with a single membrane and one replicon. Its biotic relationships extend across a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos (cattle), various Metazoa, Lutjanus russellii (a fish species), Danio rerio (zebrafish), Sus scrofa (pigs), Insecta (insects), Canis lupus familiaris (domestic dogs), Felis catus (domestic cats), and Phocoena phocoena (porpoises). This strain is clinically significant due to its association with numerous health effects, particularly in humans. It is linked to serious conditions such as bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and various nosocomial infections. Its presence in different body parts, including the urinary tract, intra-abdomen, pelvic regions, and oral cavity, highlights its pathogenic potential and ability to cause a range of infectious lesions, including neonatal infections and catheter-associated urinary tract infections (CAUTI). The ecological insight from E. faecalis strain VV8’s diverse host range and pathogenicity underscores its adaptability and the potential for zoonotic transmission, which merits monitoring in both clinical and environmental settings.
