Phylogenetic analysis of 16S rRNA genes from all species of the genus Treponema presently recognized along with isolate RCC2812T. This phylogenetic tree was generated with FastTree using the maximum-likelihood method, based on the generalized time-reversible model (there were a total of 1242 nucleotide positions in the final dataset). Bootstrap values (only those >70 % are shown) based on 1000 replicates are shown at the branch nodes for the maximum-likelihood method. GenBank accession numbers are indicated in parentheses. Bar: 0,04 nucleotide substitutions per site.
