Quantified in vivo bioluminescence. ROIs were calculated for each mouse using Living Image 3.0 software, giving a unit of photons sec−1. The relative bioluminescence per bacteria was calculated for each promoter construct by normalizing the total flux to CFU mL−1 from either the calculated inocula (0-hour) or intestinal homogenates (4- and 24-hour). N=7–10 mice. Significant differences in luminescence between the 0-hour and 4- or 24-hour were determined by two-tailed Student’s t-test. *, P<0.05. **, P<0.005.
