On the basis of phenetic and chemotaxonomic criteria a new nonmotile anaerobic gram-negative rod-shaped bacterium from dental root canals is described. The new species has characteristics in common with species of the genus Bacteroides, but there are also many differences. According to a detailed biochemical analysis the new species is closer to the genus Mitsuokella than to Bacteroides. We propose a new species, Mitsuokella dentalis. The type strain of M. dentalis is strain DSM 3688.
