Fig. 2From: Investigation of the invasion mechanism mediated by the outer membrane protein PagN of Salmonella TyphimuriumPagN 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)Back to article page
