(Submitter supplied) Genome expression study of Bacteroides fragilis strain 638R comparing a fur deletion mutant with the wild-type strain grown in minimal defined media with iron-replete or iron-limiting conditions following oxygen exposure. The construction of the fur mutant analyzed in this study was described in Robertson KP, Smith CJ, Gough AM, Rocha ER. Characterization of Bacteroides fragilis hemolysins and regulation and synergistic interactions of HlyA and HlyB. more...

(Submitter supplied) The phylum Bacteroidetes is a major component of the human gut microbiota which has a broad impact on the development and physiology of its host, and a potential role in a wide range of disease syndromes1-3. The predominance of Bacteroidetes and the genus Bacteroides in the distal gut is due in large part to the expansion of paralogous gene clusters, termed Polysaccharide Utilization Loci (PULs), dedicated to the uptake and catabolism of host derived and dietary polysaccharides4,5. more...
