The intestinal microbiota inhibits the proliferation of colon cancer cells. The capacity of microbial fecal cells (MFCs) extracted from 22 omnivores (O), 20 vegetarians (VG) and 19 vegans (V) and the corresponding microbial protein cell extracts (MPCEs) and flagellin (FlC) at two different concentrations (0.015 µg/ml of DMEM for O and 0.090 µg/ml for VG and V MPCE samples) to affect cell viability was assessed by the sulforhodamine B assay at different time-points in human HT29 colon cancer cells. Percentages of growth inhibition for colon cancer cells treated with MFCs, MPCEs or FlC compared to control (cells treated with PBS only), presented as the mean value ± s.d. from three replicates for each of the 61 samples. All data shown are representative of three independent experiments using fecal samples collected at three time-points in one month. Corrected P-values were obtained by using ANOVA test and Tukey test for multiple test correction.
