Enterococcus faecium strain ARL08-1256

Enterococcus faecium strain ARL08-1256 is a Gram-positive bacterium that exhibits a cocci shape and is classified as a facultative anaerobe. This strain is notable for its habitat in fermented mare milk, indicating its adaptation to specific ecological niches relevant to dairy fermentation processes. It possesses flagella, which may contribute to its motility in diverse environments. E. faecium ARL08-1256 has a single replicon and is capable of infecting various hosts, including humans (Homo sapiens), domesticated animals such as cattle (Bos taurus) and pigs (Sus scrofa), as well as birds (Aves) and certain fish species like Lutjanus russellii. This broad host range highlights its ecological flexibility and potential for interaction with both wild and domesticated species. In terms of health effects, this strain is associated with several serious clinical conditions, including endocarditis, bloodstream infections, and urinary tract infections. It is recognized as a pathogen in humans and is implicated in nosocomial infections, which are infections acquired in healthcare settings. The strain is also linked to biliary tract infections and systemic infections, underscoring its significance in medical microbiology. The ability of E. faecium ARL08-1256 to thrive in fermented products while also posing a risk for human health reflects the complex interplay between beneficial and pathogenic microorganisms in food and clinical environments. Its presence in both natural and clinical settings emphasizes the importance of monitoring such strains to mitigate potential health risks.
