The Figure 4B shows that S. enterica L-SXTP, which expresses and releases the cell-permeable Bax BH3 through the MisL autotransporter, reduced dramatically the cellular viability after 8 h of infection to values of 61% ± 2.8, and this effect was greater 10 h after infection (31% ± 4.3) compared with the non-treated cell control (medium), which remained with viability values above 95% ± 0.5 at all the analyzed times. Here, BAX is linked to infection.
