One dose of peptide p6 protects mouse intestine for at least 12 h. (A) Schematic illustration of the experimental flow. (B) Diarrhea symptoms in mice at different time intervals between peptide and EPEC gavage. Red circles indicate elongated feces as a sign of diarrhea, and green arrows indicate normal feces. (C) Intestinal morphology of different groups with differing intervals between peptide and EPEC gavage. Red circles and arrows indicate semisolid feces, agglomerated pellets, and swollen cecum, whereas green circle and arrows indicate normal morphology.
