Definition
Bac.te.ro.i.de′tes. bacteroid-, “bacteria resembling a rod”; -etes, “the phylum of.” The phylum Bacteroidetes is a phenotypically diverse group of gram-negative rods that do not form endospores. Current taxonomy of the phylum is based on 16S rDNA gene sequences. The phylum contains four classes: Bacteroidia, Cytophagia, Flavobacteria, and Sphingobacteria (Krieg et al. 2011).
Introduction
The phylum Bacteroidetes is composed of gram-negative rods found in diverse environmental habitats as well as the flora of insects and animals. This phylum diverged quite early in the evolutionary lineage of bacteria, and thus the Bacteroidetes are not closely related to the Proteobacteria gram-negative rods such as Escherichia coli or Pseudomonas aeruginosa...
