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

Figure 5

Fate of B. cereus ss spores introduced in groundwater. Counts of CFUs and thermoresistant CFUs (i.e., spores) were performed over time. Two independent experiments (triangles, replicate 1; circles, replicate 2) are presented. Full symbols and full lines: B. cereus ss total CFU; open symbols and dashed lines: B. cereus ss thermoresistant CFU; grey horizontal line: detection threshold (3.48 log CFU/L).
