Enterococcus faecium strain CVM N55290

Enterococcus faecium strain CVM N55290 is a Gram-positive bacterium characterized by its cocci shape and facultative anaerobic metabolism. This strain is notable for its presence in fermented mare milk, suggesting a role in dairy fermentation processes. It possesses flagella, which may contribute to its motility in various environments. E. faecium is known to have a diverse range of hosts, including Homo sapiens, Gallus gallus, Bos taurus, and several other species across Metazoa and Aves, indicating its ability to inhabit various ecological niches. The strain has been associated with multiple health issues, particularly in humans, where it has been linked to endocarditis, nosocomial infections, bloodstream infections, urinary tract infections, biliary tract infections, and nosocomial bacteremia. Its pathogenic potential highlights its significance in clinical microbiology. With a single replicon, strain CVM N55290's genetic organization may facilitate the study of its resistance mechanisms and virulence factors. The strain's adaptability and pathogenicity underscore the importance of monitoring Enterococcus species in both clinical and environmental settings. Considering its association with fermented products, E. faecium may play a dual role in food systems as a beneficial fermenter while also posing risks to human health through opportunistic infections. This dual nature exemplifies the complexity of microbial interactions in both ecological and health contexts.
