The Water Cycle, a Potential Source of the Bacterial Pathogen Bacillus cereus

Figure 2

Dendrogram illustrating the diversity of B. cereus sl natural isolates. M13-PCR was performed on 40 isolates from soil (black boxes) and on 40 isolates from percolated water (white boxes). Genuine distinct isolates were distinguished from putative clones when the percentage similarity (indicated above) was <85% (black vertical bar).
