Tóm tắt

ABSTRACTBreast‐feeding reduces the risk of enteric bacterial infections in newborns in part because of human milk oligosaccharides (HMOs), complex glycans that are present in human milk, but not in infant formula. Enteropathogenic Escherichia coli (EPEC) are attaching/effacing pathogens that cause serious diarrheal illness with potentially high mortality in infants. We isolated HMOs from pooled human milk and found that they significantly reduce EPEC attachment to cultured epithelial cells. In suckling mice, administration of HMOs significantly reduced colonization with EPEC compared with untreated controls. These data suggest an essential role for HMOs in the prevention of EPEC infections in human infants.
