Enterococcus faecium strain 349T

Enterococcus faecium strain 349T is a Gram-positive, facultative anaerobic bacterium characterized by its cocci shape and presence of flagella. This strain is notably found in fermented mare milk, indicating its adaptation to specific dairy environments. E. faecium is of particular interest due to its association with various hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and other Metazoa, highlighting its broad ecological range. This strain is recognized for its pathogenic potential in humans, being linked to several health issues such as endocarditis, nosocomial infections, bloodstream infections, urinary tract infections, biliary tract infections, and nosocomial bacteremia. Additionally, it has been implicated in infected pancreatic necrosis and systemic infections. These health effects emphasize the significance of E. faecium in clinical settings, particularly as a nosocomial pathogen. E. faecium strain 349T has a single replicon, which may contribute to its genetic stability and adaptability in various environments. Its ability to thrive in fermented mare milk while also being a human pathogen illustrates the complex interactions between microbial species and their hosts. This duality underscores the importance of monitoring such strains in both food safety and public health contexts, as their presence in fermented products may influence their pathogenic potential when transmitted to humans or other animals.
