Transepithelial electrical resistance (TER) of Campylobacter concisus-infected colonic epithelial cell monolayers in monoculture and co-culture (with M1-macrophage-like THP-1 cells on the basal side) conditions. (A) Changes in TER in uninfected controls (white/bright grey bars) in monoculture and co-culture were recorded and compared with C. concisus-infections (dark grey/black bars) at 0 h (before infection), 24 h and 48 h post-C. concisus infection with a multiplicity of infection (MOI) of 200 (n = 23 in three independent experiments, ns = not significant, *** p < 0.001).
