Enterococcus faecium strain VV6

Enterococcus faecium strain VV6 is a Gram-positive bacterium that is classified as a facultative anaerobe, exhibiting a cocci shape. It is notable for its presence in fermented mare milk, a habitat that suggests its adaptation to specific environmental conditions associated with dairy fermentation processes. This strain has been linked to various health effects, particularly in humans. It is associated with serious conditions such as endocarditis, bloodstream infections, urinary tract infections, and biliary tract infections. Additionally, it is implicated in nosocomial infections, which are infections acquired in healthcare settings, and has been identified in cases of systemic infections and infected pancreatic necrosis. The strain's pathogenicity in humans highlights its potential as a significant clinical concern. E. faecium VV6 has a wide range of hosts, including mammals and birds, such as Homo sapiens, Bos taurus (cattle), Gallus gallus (chickens), and Sus scrofa (pigs), among others. This broad host range suggests that the bacterium may play a role in the microbiota of various animal species, as well as in cross-species transmission dynamics. The presence of a single replicon in E. faecium VV6 may indicate a streamlined genomic structure that could influence its adaptability and survival in diverse environments. The multifaceted interactions of this strain with different hosts and its ability to cause serious infections in humans underscore its ecological and health significance.
