Enterococcus faecalis strain EF5152

Enterococcus faecalis strain EF5152 is a Gram-positive, non-motile coccus that functions as a facultative anaerobe, utilizing organic compounds as a chemoorganotrophic energy source. This strain is mesophilic, with an optimal growth temperature of 37°C, which aligns with the human body temperature, suggesting its adaptation to thrive in warm-blooded hosts. E. faecalis strain EF5152 has a single membrane and one replicon, indicating a simple cellular structure typical of many bacteria. Its biotic relationship is free-living, allowing it to inhabit diverse environments, including the gastrointestinal tracts of various hosts. Notably, this strain has been identified in numerous species, including Homo sapiens, Gallus gallus (chickens), and several mammals and fish, highlighting its ecological versatility. This strain is associated with multiple health effects in humans, including bacteremia, urinary tract infections (UTIs), endocarditis, and various other infections affecting different body parts. Its pathogenicity is particularly concerning in nosocomial (hospital-acquired) infections, as it can cause severe conditions such as septicemia and infective endocarditis. E. faecalis is also implicated in infections in surgical sites and dental abscesses, indicating its potential to thrive in both community and healthcare settings. The diverse habitat and broad host range of Enterococcus faecalis strain EF5152, combined with its significant pathogenic potential, underline the importance of monitoring this organism in clinical and environmental contexts to mitigate its impact on public health.
