Influence of live E. coli and live L. rhamnosus on rat uterine epithelial cell TER. Polarized uterine epithelial cells were grown in NUNC cell culture inserts. Apical medium was replaced with live E. coli (A) or live L. rhamnosus (B) in saline. Controls were treated apically with sterile saline. Basolateral compartments were fed with antibiotic-free F12K complete medium. TER (expressed in ohms per well) was measured after 24 h of incubation with bacteria (background TER, 180 Ω/well). Values shown are mean TERs ± standard errors for groups of three to four wells per treatment group. E. coli results are representative of four separate experiments (n = 4), and L. rhamnosus results are representative of six experiments (n = 6).
