Bacteroides fragilis str. DCMOUH0042B

Bacteroides fragilis str. DCMOUH0042B is a Gram-negative, rod-shaped bacterium that exists primarily as single cells and is classified as an anaerobe. This strain thrives optimally at a temperature of 37.0°C, aligning with the physiological conditions commonly found in the human body, which is its natural habitat. As a chemoorganotroph, Bacteroides fragilis str. DCMOUH0042B metabolizes organic compounds to derive energy, playing a crucial role in the degradation of complex carbohydrates within the host-associated environment. The presence of Bacteroides fragilis species in the gut microbiota is essential for maintaining intestinal health, particularly in the degradation of dietary fibers and other organic materials that are not readily digestible by the host. This metabolic capability may contribute to the overall balance of microbial communities in the gastrointestinal tract, influencing nutrient absorption and host metabolism. Furthermore, the unique anaerobic nature of this strain suggests adaptations that allow it to thrive in low-oxygen environments, which is characteristic of the gut ecosystem. Understanding the specific roles and interactions of Bacteroides fragilis str. DCMOUH0042B within its ecological niche could provide insights into its contributions to host health and the potential impacts of dysbiosis in gut microbiota.
