Enterococcus faecium strain TV82

Enterococcus faecium strain TV82 is a Gram-positive bacterium that primarily inhabits fermented mare milk. It is classified as a facultative anaerobe, meaning it can survive in both aerobic and anaerobic environments. The bacterium has a cocci shape and possesses flagella, which may aid in its motility and colonization. This strain has been associated with various hosts, including Homo sapiens (humans), as well as several animal species such as Gallus gallus (chickens), Bos taurus (cattle), and Sus scrofa (pigs), among others. The diversity of hosts underscores the strain's ecological versatility and potential for transmission across species. E. faecium strain TV82 is notable for its pathogenicity in humans, having been implicated in a range of health issues. These include endocarditis, bloodstream infections, urinary tract infections, and biliary tract infections. Furthermore, it is associated with nosocomial infections and bacteremia, highlighting its role in hospital-acquired infections. Infections can lead to severe systemic complications, such as infected pancreatic necrosis. The presence of this strain in fermented mare milk may indicate its role in both the fermentation process and its potential as a human pathogen. Its adaptability to various environments and hosts suggests that E. faecium strain TV82 plays a significant role in the microbiome of fermented foods, while also posing a risk for human health in clinical settings. Understanding its behavior in different ecological niches can inform strategies for managing infections linked to this strain.
