Effects of LGG on E. coli K1 translocation across Caco-2 monolayers (a) and transepithelial electrical resistance (TEER) of Caco-2 monolayers (b). (a) Epithelial cells were incubated with various doses of L. rhamnosus for 3 hours before adding 10⁷ E44. Transcytosis assays were carried out as described above. All values represent the means of triplicate determinations at 4 hours. Experiments were repeated three times. Error bars indicate standard deviations. *P < .05. (b) TEER was not significantly altered after 0 to 6 hours incubation.
