BAX and infection: Taking into account days post infection, there was a statistically significant difference in Bax protein expression in immunocompetent infected mice at 8 versus 16 versus 24 dpi (Kruskal-Wallis H-test; H = 12.02; p = 0.0024); in contrast, in immunosuppressed mice, differences in Bax protein expression according to days post infection were not statistically significant.
