Enterococcus faecalis strain HA-1

Enterococcus faecalis strain HA-1 is a Gram-positive, cocci-shaped bacterium that functions as a facultative anaerobe and is classified as a chemoorganotroph. It has a mesophilic temperature range, with an optimal growth temperature of 37°C. The strain is non-motile and does not possess flagella, and it contains two replicons and a single membrane. This strain exhibits a free-living biotic relationship and is found in multiple habitats. It has been identified as a pathogen in humans and is associated with a variety of health effects, including bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and septicemia. It can cause infections in various body parts, such as the urinary tract, intra-abdomen, pelvic regions, surgical sites, and the oral cavity. Additionally, it is implicated in nosocomial infections and can lead to serious conditions like infectious lesions and interstitial pneumonia. E. faecalis strain HA-1 has a diverse host range, affecting not only Homo sapiens but also species including Gallus gallus, Bos, various Metazoa, and several aquatic and terrestrial animals. This wide host range underscores its ecological versatility and potential for cross-species transmission. The strain’s pathogenicity and ability to thrive in different environments highlight its significance in both healthcare settings and ecological interactions.
