Enterococcus faecalis strain AR00-128

Enterococcus faecalis strain AR00-128 is a Gram-positive, cocci-shaped bacterium known for its chemoorganotrophic metabolism. It is classified as a facultative anaerobe, allowing it to thrive in both aerobic and anaerobic environments, with an optimal growth temperature of 37°C, characteristic of mesophilic organisms. This strain possesses a single membrane and does not exhibit mobility due to the absence of flagella. E. faecalis strain AR00-128 is free-living and has been isolated from multiple habitats, indicating its versatility in different ecological niches. It has a wide range 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, suggesting its role as a commensal organism in diverse ecosystems. Clinically, E. faecalis is associated with a variety of serious health conditions in humans, including bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and septicemia, among others. These infections often arise in nosocomial settings, highlighting its pathogenic potential and ability to cause infectious lesions in multiple body regions, including the urinary tract and oral cavity. The prevalence of E. faecalis in both healthy and diseased hosts underscores its ecological significance and adaptability. Its capacity to colonize various environments and hosts may contribute to its role in human health and disease, particularly in hospital settings where it can be a source of nosocomial infections.
