Enterococcus faecium strain TV98

Enterococcus faecium strain TV98 is a Gram-positive, facultative anaerobic bacterium characterized by its cocci shape. It is notable for its natural habitat in fermented mare milk, which suggests a specific ecological niche where it may play a role in the fermentation process. This strain possesses true flagella, indicating motility, although its ecological implications in fermented milk are not described. E. faecium strain TV98 is associated with a range of hosts, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and various other species across the Metazoa kingdom, including fish and birds. This wide host range highlights its adaptability and potential for transmission across different species. From a clinical perspective, E. faecium strain TV98 is linked to several health issues, primarily in humans. It is known to cause endocarditis, nosocomial infections, bloodstream infections, urinary tract infections, biliary tract infections, and infected pancreatic necrosis. The strain's pathogenicity is significant, as it has been implicated in systemic infections and nosocomial bacteremia, indicating a role in healthcare-associated infections. The presence of E. faecium in both fermented foods and as a human pathogen underscores its dual nature. While it may contribute beneficially to food fermentation, its potential to cause serious infections in humans reflects the complex interactions between beneficial and pathogenic microorganisms. This duality emphasizes the importance of careful monitoring of Enterococcus species in both food safety and clinical settings.
