Enterococcus faecium strain ARL07-1163

Enterococcus faecium strain ARL07-1163 is a Gram-positive bacterium classified as a facultative anaerobe, which means it can grow in both aerobic and anaerobic environments. This strain exhibits a cocci shape and possesses flagella. It is found predominantly in fermented mare milk, indicating its adaptation to this specific habitat. E. faecium ARL07-1163 has been associated with various health concerns in humans, including endocarditis, bloodstream infections, urinary tract infections, biliary tract infections, and nosocomial infections. Its pathogenicity is significant, as it can lead to serious systemic infections and is implicated in nosocomial bacteremia. Additionally, it can affect a range of hosts beyond humans, including various animal species such as Gallus gallus (chickens), Bos taurus (cattle), Sus scrofa (pigs), and others, highlighting its potential for cross-species transmission. With a single replicon, E. faecium ARL07-1163 showcases a streamlined genomic structure, which may contribute to its adaptability and survival in diverse conditions. The presence of this strain in both human health contexts and animal reservoirs suggests a complex ecological relationship, emphasizing the importance of monitoring Enterococcus species in food sources, such as fermented mare milk, to prevent potential infections in humans and other animals. Understanding the habitats and hosts of E. faecium can aid in the development of strategies to control its spread and mitigate its health impacts.
