Bacteroides fragilis str. 3783N1-6

Bacteroides fragilis strain 3783N1-6 is a Gram-negative, rod-shaped bacterium that typically exists in single-cell arrangements and is classified as an anaerobic chemoorganotroph. This strain thrives optimally at a temperature of 37.0°C, which aligns with the typical physiological temperature of the host organisms it associates with. Bacteroides fragilis is well-documented for its role within the gastrointestinal microbiota, contributing to the breakdown of complex carbohydrates and facilitating nutrient absorption through fermentation processes. Its anaerobic metabolism allows it to occupy niches within the host that are devoid of oxygen, which is crucial for maintaining homeostasis in the gut environment. The association of Bacteroides fragilis strain 3783N1-6 with host organisms highlights its potential role in symbiotic relationships, where it may contribute to the immune system's modulation and the overall health of the host. Given the strain's specific traits, further exploration of its metabolic pathways and interactions within the microbial community could provide insights into its functional contributions to host physiology and microbial ecosystem dynamics.
