Abstract

In order to assess the relationship between the genus and other members of the family , the 16S rRNA genes of type strains of the recognized species, , , and , were sequenced. A comparative phylogenetic analysis based on these 16S rRNA gene sequences and those available for strains belonging to several genera of the family showed that members of the genus form a cluster that contains all the known species. However, the type strain of (ATCC 33110) was included within this cluster in a very close relationship with the type strain of (ATCC 51609). In addition to the phylogenetic evidence, biochemical and DNA–DNA hybridization analyses of species within this cluster indicated that the type strain of is in fact a member of the genus and, within it, of the species . Therefore, following the current rules for bacterial nomenclature and classification, the transfer of to the genus comb. nov. is proposed (type strain, ATCC 33110=CIP 79.27=LMG 2785=CCUG 14183). Biochemical analysis of four strains and one strain independent of the respective type strains further indicated that and represent the same species and are therefore heterotypic synonyms. Nomenclatural priority goes to the oldest legitimate epithet. Consequently, Müller . 1996 is a later synonym of ( Izard . 1980 ) Pavan . 2005.
