Enterococcus faecalis strain 5A-16

Enterococcus faecalis strain 5A-16 is a Gram-positive, non-motile cocci bacterium classified as a facultative anaerobe, indicating its ability to thrive in both the presence and absence of oxygen. This strain is chemoorganotrophic, utilizing organic compounds as its energy source. It is mesophilic, with an optimal growth temperature of 37°C, which aligns with the average human body temperature. E. faecalis strain 5A-16 can be found in multiple habitats and exhibits a free-living biotic relationship. It has a single membrane and one replicon. This strain is notably pathogenic in humans, associated with a wide array of health complications, including bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and various nosocomial infections. The bacterium has been implicated in infections across multiple body parts, including the urinary tract, intra-abdominal regions, surgical sites, and even the oral cavity. The hosts for this strain extend beyond humans to include various species such as Gallus gallus (chickens), Bos (cattle), and several fish and mammalian species, indicating its ecological versatility. This broad host range suggests that E. faecalis strain 5A-16 may play a significant role in both environmental and clinical microbiomes, potentially contributing to the spread of antibiotic resistance in diverse settings. Understanding its pathogenic potential and ecological interactions is crucial for developing strategies to manage infections caused by this strain.
