MTT proliferation assay. PSI c1.1, B1OXI and CLAB cells were seeded at 6 × 105 cells/ well. As confluent monolayers, the cells were exposed to the selected probiotic bacteria (1 × 108 CFU/mL) or to the combination of the probiotic bacteria (1 × 108 CFU/mL) and C. jejuni (2 × 108 CFU/mL), for 24 h (a) and 48 h (b). Error bars indicate the standard deviation from at least three independent experiments. Data are expressed as % cell survival, compared to the control
