Distribution of the highest-peak positions in the 32 to 38 kDa range grouped per genotype (GT). Each isolate is represented by four peak positions. GT1 (O1/O139 Tox+) comprises 96 peak positions of 24 isolates; GT1 (O1 Hikojima Tox+) comprises 4 peak positions of 1 isolate; GT2 (O1, Tox-) 32 peak positions of 8 isolates; GT3 (O1 Tox-) shows 12 peak positions of 3 isolates with the same genotype but different serotypes. GT4, GT5 and GT6 each comprise 8 peak positions of 2 isolates; SLVs comprise 20 peak positions of 5 not related isolates; V. mimicus comprises 4 peak positions of one V. mimicus strain; Outlier comprises 4 peak positions of one outlier, in the second experiment for this isolate the maximal difference in peak positions was 52 Da.
