Measurements from micro-CT micrographs of three individual sand flies in each of the five experimental (infected) or control (uninfected) groups showing thoracic and abdominal midgut and PSG-parasite plug volumes and diameters of the stomodeal valve (SV) opening and of the anterior midgut just posterior to the SV (see Fig 3D for example).

T7CON flies were 7 days after a non-infected blood meal. T9INF and T12INF flies were 9 and 12 days, respectively, after an infected blood meal. T6INF+ and T9INF+ flies were 6 and 9 days, respectively after an infected blood meal and 1 and 4 days, respectively, after a second, non-infected blood meal.
