Core set of CDSs of proteolytic C. botulinum/C. sporogenes. Microarray data were filtered to calculate numbers of CDSs which were shared by all strains at a given signal channel ratio. A cut-off value of 0.55 (arrows) was chosen as most appropriate to exclude CDSs that are absent or diverged from their ATCC 3502 counterparts. From the plots presented here this ratio value indicates a core set of 2155 CDSs that are shared by all 61 strains tested (filled diamonds), and 3055 CDSs that are shared by all 10 C. botulinum ha plus/orf-X minus A1 strains in clades 7 and 8 (filled triangles).
