Enterococcus faecium strain ARL07-1139

Enterococcus faecium strain ARL07-1139 is a Gram-positive bacterium that primarily inhabits fermented mare milk. This strain is classified as a facultative anaerobe and displays a cocci shape. Notably, it possesses flagella, which may contribute to its motility and adaptability within various environments. E. faecium strain ARL07-1139 is associated with a range of hosts, including Homo sapiens (humans), Gallus gallus (domestic chickens), Bos taurus (cattle), and several other species across Metazoa and Aves. This broad host range highlights its ecological versatility and potential for transmission across different animals and humans. In terms of health implications, E. faecium strain ARL07-1139 is linked to several serious infections, including endocarditis, bloodstream infections, urinary tract infections, and biliary tract infections. It is notable for its role in nosocomial infections, indicating its ability to thrive in healthcare settings and contribute to healthcare-associated morbidity. The strain's pathogenicity in humans underscores its clinical relevance, particularly in immunocompromised populations. The presence of a single replicon suggests a streamlined genetic architecture, which may facilitate its adaptability and survival in varied environments. Understanding the traits of E. faecium strain ARL07-1139 can provide insights into its ecological role in fermented products and its potential impacts on human health, emphasizing the importance of monitoring this organism in both food safety and clinical contexts.
