Enterococcus faecium strain 07-03-81

Enterococcus faecium strain 07-03-81 is a Gram-positive, facultative anaerobic bacterium with a cocci shape. It is notably found in the habitat of fermented mare milk. This strain has been associated with various health effects, particularly in humans, where it can contribute to serious conditions such as endocarditis, bloodstream infections, urinary tract infections, biliary tract infections, and nosocomial infections, including nosocomial bacteremia. The pathogenicity of E. faecium strain 07-03-81 emphasizes its relevance in clinical settings. The strain has a single replicon and is capable of surviving in diverse ecological niches, including various hosts such as Homo sapiens (humans), Gallus gallus (chickens), Bos taurus (cattle), and others across the Metazoa kingdom. Its presence in both animal and human hosts highlights its adaptability and potential for zoonotic transmission. The ability of E. faecium to thrive in different environments may facilitate its persistence and spread, especially in fermented dairy products. The occurrence of this strain in fermented mare milk suggests a possible role in traditional food processes, while its association with serious infections raises concerns regarding its pathogenic potential in healthcare settings. The dual nature of E. faecium strain 07-03-81 as both a component of a culturally significant food source and a potential pathogen illustrates the complex interplay between beneficial and harmful microorganisms in our ecosystems.
