Figure 1. Cytotoxic effects of various B. cereus strains on intestinal epithelial cells (IEC).

Figure 1

Ptk6 cells were treated with 14 different B. cereus strains and two isogenic mutants, morphological changes were monitored over time using light microscopy. A. At an MOI of 1 all strains tested caused epithelial cell rounding (yellow) and detachment (red) within 2–4 h after infection except for the plcR deletion mutant. Intact monolayer (green). B. Representative images of Ptk6 cell monolayers. Bar, 20 µm.
