FIG. 2.

Population snapshot of the B. cereus group. Numbers refer to the ST allelic profiles (newly determined or available in the MLST database). Clusters of linked isolates correspond to potential CCs (i.e., STs sharing at least six identical alleles) (18). Primary founders, colored blue except for 142, which is purple (see below), are positioned centrally in the cluster, and subgroup founders are shown in yellow. Newly determined unique isolates are green, while new isolates with a counterpart in the public database are shown in purple. ST profiles sharing at least five identical alleles are grouped according to a common color background. STs present only in a public B. cereus MLST database are shown in orange. Dot sizes are proportional to the number of isolates with the same ST allelic profile.
