Enterococcus faecium strain ARL09-193

Enterococcus faecium strain ARL09-193 is a Gram-positive bacterium characterized by its cocci shape and the presence of flagella. This strain is a facultative anaerobe, allowing it to thrive in various oxygen conditions. It has a single replicon and is notably found in the habitat of fermented mare milk. This strain has a broad host range, including Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and several other species across the Metazoa, Aves, and Mammalia groups. Its pathogenicity is significant, as it is associated with a variety of health effects in humans, including endocarditis, bloodstream infections, urinary tract infections, and nosocomial infections. The strain is also implicated in biliary tract infections, nosocomial bacteremia, infected pancreatic necrosis, and systemic infections. The prevalence of Enterococcus faecium strain ARL09-193 in fermented mare milk and its potential to cause infections in multiple hosts highlights its ecological versatility. Its ability to survive in both dairy environments and human-associated infections illustrates the complex relationships between microbes and their hosts. This strain's presence in fermented foods may also point to its role in the microbiota of these environments, possibly influencing both food safety and human health outcomes. Understanding the ecological dynamics of such strains is crucial for assessing their impact on health and disease.
