Genetic structure of B. cereus group isolates. a Distribution of STs in control and three treatment groups. Following MLST, 291 B. cereus group isolates were classified into 63 unique STs. b NJ phylogenetic tree based on concatenated sequences of seven loci. Clustering revealed three major groups (I, II, and III). STs containing isolates with mobility potential are marked using a black rectangle. Genealogical groups identified by goeBURST analysis at SLV level correspond to three subclades in dendrogram and are marked in shadow
