Phylogenetic trees based on sequences of 16S rRNA (a) and glyceraldehyde-3-phosphate dehydrogenase encoding gene gap (b) of the three T. pyogenes strains of the present study and reference strains of the genra Trueperella and Arcanobacterium obtained from GenBank (NCBI). Trees were constructed using the maximum-likelihood method based on evolutionary distances calculated with the general time reversible model. Numbers at branch nodes represent the percentage of replicate trees in which the associated taxa clustered together in bootstrap tests (1000 replicates). Only bootstrap values ≥70% are shown
