Enterococcus faecium strain M299741

Enterococcus faecium strain M299741 is a Gram-positive, facultative anaerobic coccus that thrives in fermented mare milk. This strain is notable for its pathogenic potential, primarily affecting humans, and is associated with various health issues, including endocarditis, bloodstream infections, urinary tract infections, and nosocomial infections. Additionally, it has been implicated in biliary tract infections, nosocomial bacteremia, and infected pancreatic necrosis, indicating its significant role in systemic infections. The strain has a singular replicon and lacks flagella, which suggests a non-motile lifestyle. However, it can still adapt to different environments due to its facultative anaerobic nature, allowing it to survive in both aerobic and anaerobic conditions. Its hosts include a wide range of species, such as Homo sapiens, Bos taurus, and various bird species like Meleagris gallopavo and Gallus gallus, highlighting its ecological versatility. The presence of Enterococcus faecium in different hosts and its capability to cause infections underscore the importance of monitoring this strain in both clinical and environmental settings. Its association with fermented mare milk also raises questions about the implications of dairy consumption and microbial safety. Understanding the ecological niches occupied by E. faecium strain M299741 may provide insights into its transmission dynamics and pathogenicity, emphasizing the need for continued research into its health impacts on humans and other animals.
