Bacteroides fragilis str. 2-F-2 #4

Bacteroides fragilis str. 2-F-2 #4 is a Gram-negative, rod-shaped bacterium that operates as a chemoorganotroph, deriving energy from organic compounds. This organism is classified as an anaerobe, indicating that it does not require oxygen for growth, and thrives optimally at a temperature of 37°C, within a mesophilic temperature range. The bacterium typically exists as single cells, lacking mobility, which is consistent with its absence of flagella despite their presence in some strains. Bacteroides fragilis str. 2-F-2 #4 has a unique biotic relationship, being free-living yet host-associated, suggesting its potential role in the microbiome or other ecological niches within host organisms. With a single replicon and a double membrane structure, this strain aligns with the characteristics of many members of the Bacteroides genus, which are known for their significant contributions to gut health and microbial diversity. The strain's accessions include JGDM00000000.1, indicating its identification within genomic databases. The ecological insight drawn from the traits of Bacteroides fragilis str. 2-F-2 #4 is its potential importance in maintaining the balance of microbial communities in host-associated environments, particularly in anaerobic conditions where it may play a role in organic matter degradation and nutrient cycling. This highlights the significance of Bacteroides species in health and disease states, underscoring their contributions to the gut microbiome.
