Figure. . . Topology of the novel amphibian Chlamydiaceae (Candidatus Amphibiichlamydia salamandrae) within the phylogenetic tree obtained by neighbor-joining and based on 16S rRNA gene data from representative species. Numbers show the percentage of times each branch was found in 1,000 bootstrap replicates. The tree has been rooted with Verrucomicrobium spinosum as outgroup. Scale bar indicates nucleotide substitutions per site.
