Comments "...with Firmicutes containing at least 250 genera and Bacteroidetes containing more than 20 genera, the observed differences at the higher division level have yet not pinpointed the specific bacteria exclusively associated with obesity." "E. coli, once thought to be a dominant species in the human gut, is clearly a minor member relative to various members of the phyla Bacteroidetes and Firmicutes" (this last quote is from PMID 19023400).
