Phylogeny of the bacterial genus Brachyspira, based on the 16S rRNA gene (alignment length of 1542 nucleotides). The bacterium from this study (toutouwai Brachyspira sp.) is shown in red and has a ‘+’ after the name. Spirochetes found in birds are marked with a bird silhouette. Black circles on nodes show bootstrap support values of more than 90%. Branches are scaled according to the number of nucleotide substitutions per site, shown in the scale bar. The tree is midpoint rooted for purposes of clarity only
