Additional file 9: Figure S7. of Functional integration of the circulatory, immune, and respiratory systems in mosquito larvae: pathogen killing in the hemocyte-rich tracheal tufts

Tracheal tuft hemocytes phagocytose melanized bacteria. (A, B) Fluorescence (A) and bright-field overlay (B) images of tracheal tuft hemocytes (CM-DiI; red) phagocytosing aggregates of melanized (black) GFP-E. coli (green) at 4 h post-infection. Notice that melanin deposits dampen the fluorescence signal. Directional arrows: A anterior, P posterior, L lateral. (PDF 232 kb)
