Enterococcus faecalis strain 5A-8

Enterococcus faecalis strain 5A-8 is a gram-positive, cocci-shaped bacterium classified as a chemoorganotroph and a facultative anaerobe. It possesses a single membrane and one replicon, and it is non-motile, lacking flagella. The strain thrives optimally at 37°C, placing it within the mesophilic temperature range. This strain is notably free-living and has a diverse range of hosts, including humans (Homo sapiens) and various other species such as chickens (Gallus gallus), cattle (Bos), fish (Lutjanus russellii and Danio rerio), pigs (Sus scrofa), dogs (Canis lupus familiaris), cats (Felis catus), and even marine mammals (Phocoena phocoena). The broad host range suggests that E. faecalis strain 5A-8 might play a role in various ecological niches. Clinically, E. faecalis strain 5A-8 is associated with significant health impacts, including bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and a range of nosocomial infections. It can lead to infections in several body regions, including the urinary tract, intra-abdomen, pelvic regions, and oral cavity. This pathogenicity in humans highlights the strain's potential impact on public health, particularly in hospital settings. The presence of this strain in diverse habitats and its ability to cause various infections underscore its ecological adaptability and the importance of monitoring its prevalence in both clinical and environmental contexts.
