Enteropathogenic E. coli (EPEC) is a gram negative bacterium assigned to the Escherichia family. EPEC infections clinically manifest with diarrhoea. The bacterium acts infectious by adhesion to intestinal mucosa cells and releasing diarrheal toxin substances (Secher et al. 2016). Human milk oligosaccharides may inhibit or prevent EPEC infections by binding to the docking site of the bacterium and/or its toxin (Triantis et al. 2018).
