Group II concatenated MLST gene phylogeny. Phylogeny of aligned (MUSCLE [57]) and concatenated MLST genes for Group II genomes inferred with FastTree2 [54]. The MLST profile included 16S rRNA genes, atpD, guaA, gyrB, ilvD, lepA, mutL, oppB, pta, pyc, recA, rpoB, trpB and tuf [22]. Taxa labeled C. botulinum are WGS samples. Taxa labeled with single-word name include serotype E strains for which the MLST genes were sequenced by MacDonald and colleagues [22]. (PDF 37 kb)
