ABSTRACT

A partial 16S rRNA gene sequence of the type strain of Oribaculum catoniae was determined by using PCR direct sequencing. A comparative sequence analysis demonstrated that this species, although saccharolytic, is phylogenetically a member of the genus Porphyromonas. On the basis of the phylogenetic and phenotypic distinctiveness of O. catoniae, we formally propose that this species should be reclassified in the genus Porphyromonas, as Porphyromonas catoniae comb. nov. An emended description of the genus Porphyromonas is presented.
