NADPH oxidase is required for efficient phagocyte recruitment and containment of C. albicans.

(A–F) CAF2-dTomato C. albicans or were microinjected into the hindbrain ventricle of (A) Tg(mpx:GFP)ⁱ¹¹⁴ (n = 11) or (B) Tg(mpeg1:GAL4/UAS:Kaede) (n = 15) prim25 stage larvae. Fish were treated with DMSO (vehicle) or DPI from two hours prior to infection to 4 hpi and imaged from 0 to 4 hpi by confocal microscopy. (A–B) Images represent at least three independent experiments with three fish of each group per experiment. Scale bars = 10 μm. (C,D) Tg(mpx:GFP)ⁱ¹¹⁴ fish with GFP-expressing neutrophils were used. (E–F) Tg(mpeg1:GAL4/UAS:Kaede) fish with Kaede-expressing macrophages were used. (C, E) Phagocytes were counted at the site of infection at 4 hpi. Total phagocytes includes all EGFP⁺ phagocytes (both with and without yeast) and EGFP phagocytes that internalized fungi. Phagocytes with Candida includes only phagocytes with internalized fungi. Data from at least three independent experiments was pooled and the average and standard error of all fish are shown. (D, F) At 4 hpi, fungi were scored as intracellular or extracellular, and the % internal was calculated per fish. Average and standard error are shown. *p<0.05 **p<0.01.
