Enterococcus faecium strain TV83

Enterococcus faecium strain TV83 is a Gram-positive, facultative anaerobic coccus typically found in fermented mare milk. This strain is notable for its role as a human pathogen, being associated with various health issues, including endocarditis, bloodstream infections, urinary tract infections, and nosocomial infections. It can also cause biliary tract infections and has been implicated in infected pancreatic necrosis and systemic infections. E. faecium TV83 has a single replicon and does not possess flagella, which is consistent with its coccoid morphology. The strain has a diverse host range, affecting multiple species across different taxa, including humans (Homo sapiens), domestic livestock such as cattle (Bos taurus) and pigs (Sus scrofa), various birds (Aves), and other metazoans. This broad host range highlights the strain's ecological versatility and potential for cross-species transmission. The presence of E. faecium in fermented mare milk suggests a relationship between this bacterium and dairy fermentation processes. While it may play a role in the fermentation of this specific substrate, its pathogenic potential in humans and other animals raises concerns regarding food safety and public health. The ability of E. faecium to survive in diverse environments and its association with serious health conditions underscore its significance in both clinical and ecological contexts. Understanding strains like TV83 is critical for managing infections and assessing risks associated with fermented dairy products.
