Enterococcus faecalis strain AR99-190

Enterococcus faecalis strain AR99-190 is a Gram-positive, non-motile cocci bacterium that exhibits a facultative anaerobic metabolism, functioning as a chemoorganotroph. This strain thrives optimally at 37°C and falls within the mesophilic temperature range. It possesses a single membrane and one replicon, which is typical for many bacteria of its class. E. faecalis strain AR99-190 is free-living and has a broad range of hosts, including Homo sapiens, Gallus gallus, and various other Metazoa, indicating its ecological versatility. This bacterium is known to be pathogenic in humans, associated with a variety of serious health issues such as bacteremia, urinary tract infections (UTIs), endocarditis, and meningitis, among others. It can cause infections in numerous body parts, including the urinary tract, intra-abdominal regions, and oral cavity. The presence of this strain in nosocomial infections further underscores its medical significance. The wide-ranging host spectrum and diverse pathogenic capabilities of E. faecalis strain AR99-190 suggest that it plays a notable role in both human health and disease. Its ability to inhabit multiple environments and associate with various hosts highlights its ecological adaptability and potential for transmission in healthcare settings. The strain's pathogenicity raises important considerations for infection control and treatment strategies, especially in nosocomial contexts where antibiotic resistance may complicate management.
