SNP analysis of all environmental (green) and stool isolates (red) of Clostridium botulinum. (a) Distribution of the isolates based on their SNP/InDel count. μ, median. (b) Neighbor-joining tree of all isolates based on Hamming distance (Saitou-Nei criterion) using PHYLOViZ software (64). (c) Chromosomal distribution of SNPs and identification of three hot spot mutation regions, labeled (i) motility (flagellar apparatus), (ii) metabolism and transport (trehalose-specific phosphotransferase system [PTS]), and (iii) quorum-sensing (agr-2 operon).
