Two milk components, α-lactalbumin (α-La) and glycomacropeptide (GMP) may inhibit intestinal infection/intoxification. 3[H] thymidine-labeled enteropathogenic Escherichia coli (EPEC), Salmonella typhimurium (ATCC 6994) or Shigella flexneri (ATCC 9199) were introduced to CaCo-2 cultures and their association with CaCo-2 cells was assessed. Undigested, pepsin-digested and pepsin- and pancreatin-digested α-lactalbumin and glycomacropeptide inhibited association. Thus, milk supplemented with α-lactalbumin and glycomacropeptide might be effective in inhibiting associations of the pathogens EPEC, Salmonella typhimurium, and Shigella flexneri to intestinal cells.
