Abstract

DNAs of type strains and representative members of groups from the human periodontal flora and from other habitats were compared by using the S1 nuclease procedure to determine their genetic relatedness. One rather common group from the human periodontal flora, previously called “ D08,” is phenotypically distinct from, and genetically unrelated to, previously described species. We propose the name for this organism; the type strain is strain ATCC 49285. Another common group from the human periodontal flora is serotype II, which was found to be genetically distinct from the type strain of (serotype I) and from other previously described species of . We propose the name for this organism; the type strain is strain ATCC 23860. serotype I strains were distinct from the other strains studied. A separate genospecies which included strains of serotypes II and III and serotype II was delineated. Strains of serotype WVA 963 constitute an additional distinct genospecies. Because there are no reliable phenotypic tests, other than serological analyses, to differentiate serotype WVA 963 and the two genospecies of , no taxonomic changes are proposed for these three genospecies.
