Enterococcus faecalis strain 5A-20

Enterococcus faecalis strain 5A-20 is a Gram-positive, non-motile cocci that functions as a chemoorganotroph and is classified as a facultative anaerobe. This strain thrives optimally at a temperature of 37°C, falling within the mesophilic temperature range. E. faecalis 5A-20 possesses a single membrane and a single replicon, indicating its relatively simple cellular structure. This strain exhibits a free-living biotic relationship and is found in multiple habitats. It has a diverse range of hosts, including Homo sapiens, Gallus gallus, Bos species, and various aquatic and terrestrial Metazoa, such as Lutjanus russellii, Danio rerio, Sus scrofa, Insecta, Canis lupus familiaris, Felis catus, and Phocoena phocoena. E. faecalis 5A-20 is known for its pathogenic potential in humans, being associated with various infections including bacteremia, urinary tract infections (UTIs), endocarditis, and meningitis, among others. It is particularly noted for causing nosocomial infections and can lead to severe conditions like septicemia and infections in multiple body systems, including the urinary tract, intra-abdomen, pelvic regions, and surgical sites. The presence of this strain in numerous hosts and its ability to cause a wide variety of infections highlight its ecological versatility and potential impact on both human health and animal welfare. Understanding such strains is crucial for developing effective treatment strategies and mitigating their pathogenic effects in healthcare settings.
