Enterococcus faecalis strain IV12

Enterococcus faecalis strain IV12 is a Gram-positive, cocci-shaped bacterium classified as a chemoorganotroph and a facultative anaerobe, thriving optimally at 37°C within a mesophilic temperature range. This strain is characterized by its single membrane and nonsporulating nature, indicating a reliance on stable environmental conditions for survival. E. faecalis IV12 is free-living and can inhabit multiple environments, which contributes to its widespread presence in various hosts, including Homo sapiens, Gallus gallus, Bos, Metazoa, Lutjanus russellii, Danio rerio, Sus scrofa, Insecta, Canis lupus familiaris, Felis catus, and Phocoena phocoena. This diverse host range presents significant implications for public health, as E. faecalis is associated with multiple health issues, including bacteremia, urinary tract infections (UTIs), endocarditis, meningitis, and various nosocomial infections. The strain is implicated in a range of infections, affecting various body parts such as the urinary tract, abdomen, and oral cavity, as well as in neonatal infections and surgical site infections. This pathogenicity in humans highlights the potential clinical challenges posed by E. faecalis IV12, particularly in healthcare settings where antibiotic resistance may complicate treatment protocols. The presence of this strain in both human and animal hosts underscores its ecological adaptability and the potential for cross-species transmission, raising concerns about its role in zoonotic infections and the need for vigilant infection control measures.
