Bacteroides fragilis CAG:47 str. MGS:47

Bacteroides fragilis CAG:47 str. MGS:47 is a Gram-negative, rod-shaped bacterium that thrives in host-associated environments, primarily as a free-living organism. This species is categorized as an anaerobe, meaning it requires environments devoid of oxygen for growth. Bacteroides fragilis CAG:47 is a chemoorganotroph, utilizing organic compounds as its energy source, which aligns with its ecological role in the gut microbiome. The organism exhibits a unique cell arrangement characterized by single cells, and it possesses two membranes typical of Gram-negative bacteria. Notably, Bacteroides fragilis CAG:47 has a flagellar presence, although it is non-motile, which may suggest a potential for movement in a non-flagellar manner or that the flagella may serve a different function in its lifecycle. Optimal growth occurs at a temperature of 37°C, placing it within the mesophilic temperature range, which is conducive to its survival in mammalian hosts. With only one replicon, the genomic simplicity may reflect its adaptation to a specific niche within the host environment. In conclusion, Bacteroides fragilis CAG:47 str. MGS:47 plays a crucial role in the gut microbiome, contributing to the complex interplay of microbial communities that influence host health. Its ability to thrive in anaerobic conditions and utilize organic substrates highlights its importance in nutrient cycling and maintaining gut homeostasis.
