Phylogenomic analysis of strains of C. botulinum group III and in relation to other Clostridia. (A) Heat plot (based on the ASC method) showing the results of pairwise average nucleotide distance calculations between the available completed and draft genomes from C. botulinum group III and representative genomes from other C. botulinum groups and Clostridium species.(B) Phylogenetic tree derived from the similarity matrix shown in (A) using the neighbor-joining method.
