Genetic relatedness of Clostridium botulinum ST7B, isolated from infant stool, with a subset of internationally known C. botulinum group I strains using the codon tree method as described and generated in the online platform PATRIC (60). The neurotoxin type, neurotoxin gene cluster type, and location of the cluster are indicated. The strains are divided into five lineages (I to V), numbered according to a previous study (70). ANI, average nucleic acid identity; chr, chromosome; ha, hemagglutinin operon; orfX, orfX operon; plas, plasmid; TGC, toxin gene cluster.
