The classification and differentiation of the anaerobic gram-negative rods.
Within the family Bacteroidaceae differentiation of the genera Leptotrichia, Fusobacterium and Bacteroides still depends largely on the accumulation of certain fermentation products. The application of newer techniques, both genetical and chemical is leading to a reappraisal of the current classification. So far attention has focussed on the genus Bacteroides and has been concerned with the status of B. fragilis and related organisms and the description of a number of new species within the B. ruminicola/oralis group. The differentiation of pigment-producing strains, all known originally as B. melaninogenicus, has led to the establishment of at least 9 species. The transfer of certain Bacteroides species to new genera is also being considered.
