Cl dependence of short circuit current (Isc; µA/cm²) in uninfected Caco-2 monolayers and those infected with EPEC strain E2348/69. The Isc of uninfected monolayers did not differ significantly between Cl -inclusive and Cl -free bathing solutions; each point represents the mean (SEM) of seven monolayers. The rapid increase in Isc induced by E2348/69 in Cl -inclusive bathing solution was significantly reduced in Cl -free solution; each point represents mean Isc (SEM) from nine monolayers. *p<0.05 v uninfected or 14.2.1(1) infected monolayers; †p<0.05 v uninfected monolayers.
