Figure 1.

Phylogenetic tree highlighting the position of B. murdochii 56-150^T relative to the other type strains within the genus and to the type strains of the other genera within the class Spirochaetes (excluding members of the Spirochaetaceae). The tree was inferred from 1,396 aligned characters [21,22] of the 16S rRNA gene sequence under the maximum likelihood criterion [23] and rooted in accordance with the current taxonomy. The branches are scaled in terms of the expected number of substitutions per site. Numbers above branches are support values from 1,000 bootstrap replicates if [24] larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD [25] are shown in blue, published genomes in bold.
