The existing diarrhoeagenic Escherichia coli (E. coli) challenge model is already suitable for dietary interventions in its current form, targeted to impact on the immediate clinical symptoms upon E. coli infection. In order to make the model also suitable for dietary interventions that are aimed at support of the protective response against reinfection, the immune response triggered by the primary infection should be suboptimal. The MIRRE pilot study is set up to determine how much the primary inoculation dose of diarrheagenic E. coli should be lowered in order to result in a reduced protective response upon a secondary infection.
