Enterococcus faecalis strain AR01-215

Enterococcus faecalis strain AR01-215 is a Gram-positive, cocci-shaped bacterium classified as a facultative anaerobe and a chemoorganotroph. This strain is non-motile, lacks flagella, and has a single membrane. It is mesophilic, with an optimal growth temperature of 37°C, indicating a preference for human body temperature. E. faecalis strain AR01-215 is noted for its diverse habitat, thriving in multiple environments. It is free-living but has significant biotic relationships with various hosts, including Homo sapiens, Gallus gallus, Bos, Metazoa, Lutjanus russellii, Danio rerio, Sus scrofa, Insecta, Canis lupus familiaris, Felis catus, and Phocoena phocoena. This wide host range underscores its ecological adaptability and potential for cross-species transmission. Clinically, this strain is associated with a variety of health effects, particularly in humans. It is implicated in numerous infections, including bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and other nosocomial infections. The bacterium is known to cause septicemia and has been linked to refractory apical periodontitis, dental abscesses, and infections in surgical sites. Its pathogenicity highlights the risk it poses, especially in healthcare settings where it can lead to serious complications, such as catheter-associated urinary tract infections (CAUTI) and neonatal infections. Understanding the characteristics and pathogenic potential of Enterococcus faecalis strain AR01-215 can inform infection control strategies and highlight the need for ongoing surveillance in clinical and environmental contexts. Its ability to thrive in diverse habitats and its association with significant health impacts underscore the importance of this organism in both clinical microbiology and public health.
