Submitter Supplied Information

Analysis of differentiated Caco-2 intestinal epithelial cell line cocultured with probiotics L. acidophilus NCFM, B. lactis 420, L. salivarius Ls-33 bacterial cells or treated with cell-free supernatant, and with E. coli O157:H7 cell-free supernatant. Lactobacillus and Bifidobacterium are important genera suggested to be beneficial for human health and E. coli O157:H7 is a pathogen causing hemorrhagic colitis and hemolytic uremic syndrome. Results provide insight into the mechanisms underlying the beneficial effects of probiotics on intestinal epithelial cells and a comparison to pathogenic E. coli.
