Disease relevance of Bacteroidetes

• Incorporation of glucose under oxic and anoxic conditions was found in alpha-Proteobacteria, gamma-Proteobacteria, and the Cytophaga-Flavobacterium cluster of the Bacteroidetes at both times, but not in marine Euryarchaeota [1].
• Two additional inserts in the RNA polymerase beta'-subunit (5-7 aa) and Serine hydroxymethyl-transferase (14-16 aa), which are commonly present in various Bacteroidetes, Chlorobi, and Fibrobacteres homologs, but not any other bacteria, provide evidence that these groups shared a common ancestor exclusive of all other bacteria [2].
• Phylogenetic analysis revealed that KMM 3553(T) formed a distinct phyletic line in the phylum Bacteroidetes, class Flavobacteria in the family Flavobacteriaceae and that, phylogenetically, this strain could be placed almost equidistant from the genera Gelidibacter and Psychroserpens (16S rRNA gene sequence similarities of 94 %) [3].
• Intracellular location of flexirubins in Flexibacter elegans (Cytophagales) [4].

High impact information on Bacteroidetes

• However, compared with lean mice and regardless of kinship, ob/ob animals have a 50% reduction in the abundance of Bacteroidetes and a proportional increase in Firmicutes [5].
• The single rpoD-like gene observed in the B. fragilis genome, and similarly in those of other members of the Bacteroidetes phylum, was found to be essential [6].
• Distribution of two triamines, spermidine and homospermidine, and an aromatic amine, 2-phenylethylamine, within the phylum Bacteroidetes [7].
