From: Genome sequence of the thermophilic fresh-water bacterium Spirochaeta caldaria type strain (H1T), reclassification of Spirochaeta caldaria, Spirochaeta stenostrepta and Spirochaeta zuelzerae in the genus Treponema as Treponema caldaria comb. nov., Treponema stenostrepta comb. nov., and Treponema zuelzerae comb. nov., and emendation of the genus Treponema

Figure 1.

Phylogenetic tree highlighting the position of S. caldaria relative to the type strains of the other species within the family Spirochaetaceae. The tree was inferred from 1,362 aligned characters [12,13] of the 16S rRNA gene sequence under the maximum likelihood (ML) criterion [14]. Rooting was done initially using the midpoint method [15] and then checked for its agreement with the current classification (Table 1). The branches are scaled in terms of the expected number of substitutions per site. Numbers adjacent to the branches are support values from 1,000 ML bootstrap replicates [16] (left) and from 1,000 maximum-parsimony bootstrap replicates [17] (right) if larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD [18] are labeled with one asterisk, those also listed as ‘Complete and Published’ with two asterisks [1923] (for S. thermophila, T. azotonutricium and T. primitia see CP002903, CP001841 and CP001883). Note: Spirochaeta coccoides was effectively renamed to Sphaerochaeta coccoides in [19] (see Validation List 147 [24].)
