Enterococcus faecium strain ARL08-67

Enterococcus faecium strain ARL08-67 is a Gram-positive, facultative anaerobic bacterium characterized by its cocci shape. It is primarily found in fermented mare milk, indicating its potential role in dairy fermentation processes. This strain possesses one replicon and does exhibit flagella, which may contribute to its motility in certain environments. E. faecium strain ARL08-67 is known to affect a wide range of hosts, including Homo sapiens, various birds (Aves and Phasianidae), and mammals such as Bos taurus and Sus scrofa. This broad host range suggests that the strain may have significant ecological versatility and adaptability, allowing it to thrive in diverse environments. From a health perspective, E. faecium strain ARL08-67 is associated with several serious health complications in humans, including endocarditis, bloodstream infections, and urinary tract infections. It is particularly notable for its role in nosocomial infections, which are infections acquired in healthcare settings. The strain's pathogenicity in humans underscores its importance as a potential pathogen in clinical microbiology and infectious disease contexts. Overall, the presence of E. faecium in fermented mare milk and its pathogenic potential in humans highlights its dual role in both food production and as a concern in public health. This underscores the need for careful monitoring and study of such strains, particularly in settings where they may contribute to human infections.
