Enterococcus faecium strain ARL07-1169

Enterococcus faecium strain ARL07-1169 is a Gram-positive bacterium primarily found in fermented mare milk. It exhibits a cocci shape and is classified as a facultative anaerobe, which allows it to thrive in both aerobic and anaerobic environments. This strain possesses flagella, indicating it has the capability for motility under specific conditions. E. faecium ARL07-1169 has a single replicon and is associated with a variety of hosts, including humans (Homo sapiens), domestic animals such as cattle (Bos taurus), poultry (Gallus gallus, Meleagris gallopavo), and other metazoans. This wide host range suggests a level of ecological versatility, allowing the bacterium to adapt to different environments and potentially contribute to diverse microbial communities. In terms of health implications, E. faecium ARL07-1169 is recognized for its pathogenic potential in humans, being linked to various serious health issues such as endocarditis, bloodstream infections, urinary tract infections, and nosocomial infections. The strain is implicated in both systemic infections and specific conditions like infected pancreatic necrosis and biliary tract infections. The presence of E. faecium in fermented mare milk, combined with its pathogenic traits, highlights its dual role as both a beneficial and harmful microorganism. While it may play a part in traditional dairy fermentation processes, its ability to cause significant health effects in humans and animals underscores the importance of monitoring its prevalence and potential virulence in clinical and agricultural settings.
