In fact, whereas FliC-immunized and non-immunized mice died as a consequence of the Stx2-induced kidney injury, H7-immunized mice showed only a slight increase in BUN concentration and peripheral neutrophils that restored to baseline at 15 days p.i. Moreover, H7-immunized mice showed a significantly lower level of intestinal colonization than non-immunized or FliC-immunized mice. Here, STX2 is linked to urogenital neoplasm.
