Abstract

The 16S rRNA and genes of 22 strains belonging to the cluster were sequenced, and their taxonomic positions were re-evaluated. For correct analysis, all of the publicly available sequences of the species were collected and compared with those obtained in this study. Species for which no consensus sequence could be identified were excluded from the phylogenetic analysis. The levels of 16S rRNA gene sequence similarity within the cluster ranged from 98.6 to 100 % with a mean value of 99.6±0.3 %, and those of the gene ranged from 93.6 to 99.9 % with a mean value of 96.3±1.5 %. The observed average nucleotide substitution rate of the gene was ten times higher than that of the 16S rRNA gene, showing a far higher degree of variation. Strains sharing 99.3 % or more sequence similarity (corresponding to an evolutionary distance of 0.0073) always formed monophyletic groups in both trees. Through the combined analysis of the two genes, clear cases of synonymy could be identified and, according to the priority rule, the assertion of the status of as a distinct species and the reclassification of as a later synonym of and as a later synonym of are proposed. Emended descriptions of and are provided.
