—(A) Phylogenetic reconstruction of BotA toxin proteins. Six A–F clades are consistent with previous reports. Including non-botulinum strains, argentinense, tetani, butyricum, and baratti (marked with a dot). Three new sequences (in black) account for new unclassified toxin diversity. (B) Genome context of BotA homologs found in cluster I strains.
