Enterococcus faecalis strain ARL04-506

Enterococcus faecalis strain ARL04-506 is a Gram-positive, cocci-shaped bacterium classified as a facultative anaerobe. This strain is a chemoorganotroph, indicating that it derives its energy from organic compounds. It is mesophilic, with an optimal growth temperature of 37°C, suitable for various environments, as it can thrive in multiple habitats. E. faecalis ARL04-506 is non-motile and does not possess flagella, and it has a single membrane and one replicon. This strain is free-living and interacts with a diverse range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos (cattle), various Metazoa, Lutjanus russellii (fish), Danio rerio (zebrafish), Sus scrofa (pigs), Insecta (insects), Canis lupus familiaris (domestic dogs), Felis catus (domestic cats), and Phocoena phocoena (porpoises). Clinically, E. faecalis ARL04-506 is associated with various health effects, including bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and other nosocomial infections. It is known to cause infections in multiple body sites, including the urinary tract, intra-abdominal regions, and surgical sites. The strain’s pathogenicity is significant in human health, contributing to a range of infections from urinary issues to more severe conditions like septicemia and infective endocarditis. The broad host range and pathogenic potential of E. faecalis ARL04-506 highlight its ecological adaptability and the importance of monitoring its presence in clinical settings, particularly given its role in nosocomial infections and its implications for public health.
