Enterococcus faecium strain ARL08-804

Enterococcus faecium strain ARL08-804 is a Gram-positive, facultative anaerobic coccus, identified primarily in fermented mare milk. This strain possesses a single replicon and is notable for its potential pathogenicity in humans, being associated with various health issues including endocarditis, bloodstream infections, urinary tract infections, biliary tract infections, and nosocomial infections. It has also been linked to infected pancreatic necrosis and systemic infections. The host range for E. faecium strain ARL08-804 is broad, encompassing species from multiple taxonomic groups, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), as well as various other mammals and avian species. This wide host range suggests that this strain may have significant ecological interactions within both domestic and wild animal populations. The presence of flagella, although not commonly associated with Enterococcus species, indicates a level of motility that might facilitate its spread in certain environments. The ability to thrive in fermented mare milk, a specific habitat, highlights the strain's adaptability and potential role in dairy fermentation processes. Overall, the pathogenicity of E. faecium strain ARL08-804, combined with its diverse ecological niches, underscores the importance of monitoring this strain within both clinical and environmental contexts, as it may have implications for both human health and animal agriculture.
