Enterococcus faecium strain TV137

Enterococcus faecium strain TV137 is a Gram-positive, facultative anaerobic bacterium characterized by its cocci shape and the presence of flagella. This strain is notably found in fermented mare milk, indicating its adaptation to this specific habitat. Enterococcus faecium is known for its diverse host range, which includes Homo sapiens (humans), various livestock such as Bos taurus (cattle) and Sus scrofa (swine), as well as avian species like Gallus gallus (chickens) and Meleagris gallopavo (turkeys). This bacterium is associated with several health complications in humans, including endocarditis, bloodstream infections, urinary tract infections, biliary tract infections, and nosocomial infections. Its pathogenicity is a significant concern, particularly in clinical settings where it can lead to nosocomial bacteremia and systemic infections. The ability of E. faecium to thrive in diverse environments and its pathogenic potential highlight its role as an important opportunistic pathogen in both human and veterinary medicine. The presence of only one replicon suggests a streamlined genetic structure, which may facilitate rapid adaptation to various hosts and environments. Given its isolation from fermented mare milk, E. faecium strain TV137 may play a role in the microbial ecology of dairy environments, potentially influencing fermentation processes. Understanding the ecological interactions of this strain could provide insights into its behavior in both natural and clinical contexts.
