<p>(<b>A</b>) qRT-PCR analysis of <i>ssrB</i> expression in WT <i>S</i>. Typhimurium (SL1344) or the Δ<i>eutR</i> strain (CJA009) harvested from infected spleens. (<b>B</b>) qRT-PCR analysis of <i>eutR</i> or <i>eutS</i> expression in WT <i>S</i>. Typhimurium (SL1344) harvested from infected spleens compared to <i>S</i>. Typhimurium (SL1344) grown in tissue culture medium (DMEM).
