PagN is able to induce both adhesion and invasion depending on the cell line. CHO cells were infected with HB101-psup (hatched bars) or HB101-pagN strain (empty bars) at 37 °C for 1 h (MOI 1:10). The percentages of total cell-associated (a) and internalized (b) bacteria have been calculated as described in Materials and Methods. Data show mean values ± SD acquired from three independent experiments with two infected wells per experiment. Data were compared using a Mann Whitney test (***p < 0.001, **p < 0.01)
