<i>In vivo</i> imaging of MPO-specific bioluminescence in mice implanted with adult <i>B</i>. <i>pahangi</i>.

<p>BALB/c mice were infected intraperitoneally by transplantation with 10 female adult <i>B</i>. <i>pahangi (B</i>.<i>p)</i>. Sham-operated mice (Sham) received no worms and control mice (Ctl) received an intraperitoneal injection of HBSS but underwent no surgery. On day 17 post-infection mice were imaged using an IVIS spectrum 20 minutes after subcutaneous injection of 200 mg/kg luminol. Representative images of 2 mice per group are shown. The colour scale indicates bioluminescence radiance in photons/second/cm²/steradian. Graphs show the bioluminescence total flux (in photons/second) within the same abdominal region of interest. Each symbol shows the total flux for a single mouse, lines indicate the means (n = 4–6 mice) and error bars show SD (*<i>p</i> < 0.05 using a one-way ANOVA with Dunn’s post-test).
