FIG 3.
mRNA variation at 24 h p.i. in the cecal mucosa of mice infected with S. Dublin, determined by qRT-PCR. Values are expressed as fold changes of mRNA levels for the indicated genes in infected mice relative to their levels in mock-infected animals. Note that the y axes of the IFN-γ and S100.A9 graphs show log10 values. Means and SE for two independent experiments, with five animals per group in each experiment, are shown. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ns, not statistically significant. (A) mRNA quantification of genes coding for proinflammatory cytokines and chemokines. (B) mRNA quantification of genes coding for antimicrobial proteins.
