In a Mexican population higher concentrations of the FUT2 dependent oligosaccharides 2’FL and LNFP I in breast milk were associated with lower incidence of infectious diarrhea [18], indicating that the presence of FUT2 dependent HMOs might provide better protection from specific pathogens like Campylobacter jejuni, E. coli and norovirus [34]. The gene discussed is FUT2; the disease is dysentery.
