Fig. 3

Maximum likelihood phylogeny of tox gene-overlapping prophage and PAI sequences from different Corynebacterium species. Tox gene-overlapping prophage and detected alternative PAI regions of 81 toxigenic Corynebacterium spp. isolates were aligned and a maximum likelihood tree was built. Species affiliation is indicated by background coloring: C. diphtheriae = blue, C. pseudotuberculosis = pink, typical C. ulcerans = orange, atypical NTTB C. ulcerans = green. Results of tox qPCR and Elek test are indicated by circle and triangle shaped bars, respectively: positive = black, negative = white. The type of detected tox-surrounding mobile genetic regions is indicated by colored boxes on the right side of the tree: prophage = turquoise, alternative PAI described in [7] = yellow, different PAI than the one described in [7] = purple
