Enterococcus faecalis strain AR01-802

Enterococcus faecalis strain AR01-802 is a Gram-positive bacterium with a cocci shape, classified as a facultative anaerobe and a chemoorganotroph. It thrives optimally at 37°C within a mesophilic temperature range. This strain possesses a single membrane and one replicon, indicating its simple genomic structure. Notably, it lacks mobility and does not have flagella. E. faecalis AR01-802 is free-living and has been isolated from multiple habitats. It is associated with a variety of hosts, including Homo sapiens, various animal species such as Gallus gallus (chickens), Bos (cattle), Danio rerio (zebrafish), and Felis catus (domestic cats), among others. This strain is notable for its pathogenicity in humans, being linked to numerous health conditions, including bacteremia, urinary tract infections (UTIs), endocarditis, and various nosocomial infections. It can cause severe infections in several body parts, such as the urinary tract, abdomen, and oral cavity, and is implicated in conditions like pyelonephritis and interstitial pneumonia. The presence of E. faecalis in diverse hosts and its potential to cause a wide array of infections in humans underscores its ecological significance. Its adaptability to different environments and hosts reflects its evolutionary success, but also raises concerns regarding its role in healthcare-associated infections, highlighting the importance of monitoring and controlling its spread in clinical settings.
