Fig 6. Induction of enterocyte apoptosis and enterocyte binding by EC25.
A, Average levels of apoptosis in untreated IEC-6 cells, and cells treated with 107 cfu/ml EC25, 106 cfu/ml C. muytjensii, or combined EC25 and C. muytjensii for 6 h. 500 cells were scored in each treatment group. B, Average binding of EC25 and C. muytjensii to IEC-6 cells at the indicated bacterial inputs. In combined treatment, only binding of C. muytjensii was scored. All data are from at least 3 independent experiments.
