Enterococcus faecium strain 10-9A

Enterococcus faecium strain 10-9A is a Gram-positive bacterium predominantly found in fermented mare milk. This strain exhibits a cocci shape and is classified as a facultative anaerobe, meaning it can grow in both the presence and absence of oxygen. It possesses true flagella, allowing for motility under specific conditions. The strain has a single replicon, indicating a streamlined genetic structure which may contribute to its adaptability in various environments. E. faecium strain 10-9A is associated with a range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and several other species across the Metazoa kingdom. This broad host range highlights its potential for transmission and ecological versatility. Clinically, E. faecium is recognized for its pathogenicity in humans, where it is implicated in several serious health issues, including endocarditis, nosocomial infections, bloodstream infections, urinary tract infections, biliary tract infections, and infected pancreatic necrosis. The strain is also associated with nosocomial bacteremia and systemic infections. The presence of E. faecium in fermented mare milk, combined with its pathogenic potential in humans and various animal hosts, suggests a complex ecological role. It may act as both a beneficial organism in specific fermented products and a significant opportunistic pathogen in healthcare settings, underscoring the importance of monitoring its prevalence and resistance patterns in clinical microbiology.
