Bacteroides fragilis str. DS-208

Bacteroides fragilis str. DS-208 is a gram-negative, rod-shaped bacterium that is classified as an anaerobic chemoorganotroph. This organism is part of the Bacteroidetes phylum and is characterized by its habitat as host-associated, indicating its presence in the gastrointestinal tract of mammals. It exhibits a unique cell arrangement, occurring as singles rather than in clusters or chains. This strain has a mesophilic temperature range, with an optimal growth temperature of 37°C. Bacteroides fragilis str. DS-208 does not possess mobility, as it lacks flagella, but it has a complex cellular structure with two membranes and a single replicon. As a free-living organism, Bacteroides fragilis str. DS-208 plays a crucial role in the gut microbiome, contributing to the breakdown of complex carbohydrates and facilitating nutrient absorption in the host. Its anaerobic nature aligns with the oxygen-poor environment of the intestines, where it thrives by utilizing organic compounds as energy sources. Understanding the traits of Bacteroides fragilis str. DS-208 provides insight into its ecological role in maintaining gut health and its potential implications in human health and disease, particularly in relation to gut microbiota composition and function. The accession number for this strain is JGDE00000000.1.
