Abstract

16S rRNA gene sequence information has indicated that has a close relationship with the genus . To clarify the taxonomic position of , we determined the sequence of as it represents an alternative phylogenetic marker for identification and classification of Gram-negative anaerobic rods. On the basis of sequences, was located within the genus , indicating that the species does not represent a distinct taxon at the genus level. Statistical tests (the Shimodaira–Hasegawa test and the approximately unbiased test) supported the finding that is monophyletic with members of the genus and thus belongs to the genus. On the basis of the phylogenetic findings, we propose that should be reclassified as comb. nov.; the type strain is KB3 ( = JCM 13648  = DSM 17970). An emended description of the genus is also provided.
