A comparative 16S ribosomal DNA (rDNA) sequence analysis was used to investigate the phylogenetic position of members of the genus . We determined 16S rDNA sequence data for the type strains of the three species and five additional strains. The close relationship between the genera , and previously demonstrated by DNA-rRNA hybridization studies was confirmed. The results of our phylogenetic analysis indicate that members of the genera , and are intermixed and that there is no clear generic cluster consisting of the species. A comparison of the sequences with the 16S rDNA sequences available from environmental clone studies indicated that members of this genus have not been detected by nonculturing approaches.
