Discussing the role of SGLT1 for oral rehydration during diarrhea caused by infections, it should be considered that sodium uptake into enterocytes is also mediated by the Na+-H+-exchanger NHE3 and that infections by enteropathogenic E. coli and rotavirus are associated with a decreased expression of SGLT1 in enterocytes [80, 82, 144]. Here, SLC5A1 is linked to infection.
