(A) Distal colonic mucosal PGE₂ synthetic capacity in uninfected control rabbits and in EHEC infected rabbits 1-5 days after inoculation. Data are mean (SEM), n=12 per group. *p<0.05 compared with control, day 1 infected, and day 2 infected values. (B) Distal colonic mucosal LTB₄ synthetic capacity in uninfected control rabbits and in EHEC infected rabbits 1-5 days after inoculation. Data are mean (SEM), n=12 per group. *p<0.05 compared with control and day 1 infected values. (C) Distal colonic mucosal ⁵¹Cr-EDTA permeability in uninfected control rabbits and in EHEC infected rabbits 2-5 days after inoculation. Data are mean (SEM), n=4 per group. *p<0. 05 compared with control and other infected values. Lower panels show Cl transport and infiltration of the mucosa by neutrophils. Abs'n, absorption.
