Validation and optimization of the L. donovani assay for compound screening. (A) Heatmaps of the distribution of BMDM according to the amount of intracellular amastigotes for each experimental condition, for different macrophage seeding densities (20,000 or 40,000 cells per well), MOIs (1:3, 1:6 or 1:9 macrophage to parasite ratio), and treatments (mock [Ø], DMSO and Amphotericin B [AmB]). (B) Boxplots of percentages of BMDMs normalized to mock control values obtained with 20,000 and 40,000 seeded macrophages and recovered after three days of treatment with DMSO (vehicle control), AmB (positive control) and cycloheximide (Cyclo, toxicity control) are represented. (C) Boxplots of percentages of BMDMs harboring parasites after 3 days for all experimental conditions except for cycloheximide. Whisker plot represents median and 5th/95th percentiles.
