Enterococcus faecalis strain AR99-1024

Enterococcus faecalis strain AR99-1024 is a Gram-positive cocci that functions as a chemoorganotroph, deriving energy from organic compounds. This strain is classified as a facultative anaerobe, indicating its ability to grow in both aerobic and anaerobic conditions, and is mesophilic with an optimal growth temperature of 37°C. It possesses a single membrane and a single replicon, which are characteristic features of this bacterial strain. E. faecalis AR99-1024 is known to be nonmotile, lacking flagella, and exists as a free-living organism in various habitats. This strain has a significant pathogenic potential in humans, being associated with a multitude of health issues, including bacteremia, urinary tract infections (UTIs), endocarditis, and meningitis, among others. It is implicated in both nosocomial infections and infections arising from various body sites, such as the urinary tract and oral cavity. The strain has a diverse range of hosts, including Homo sapiens, various mammals (e.g., Gallus gallus, Bos, Sus scrofa), and aquatic species like Lutjanus russellii and Danio rerio. This broad host range underscores the ecological versatility of E. faecalis and its capacity to thrive in different environments, which can facilitate its transmission and establishment in various ecosystems. The presence of this bacterium in both healthy and infected individuals highlights its role in both commensal and pathogenic contexts, emphasizing the need for continued monitoring and research on its impact on public health.
