Analysis of erythroid cells at day 15 pi. Blood, spleen and bone marrow cells from mice infected with the GFP transgenic parasites were stained with specific antibodies. (A) The mean fluorescence intensity (MFI) of CD71^hi cells was measured in the erythroid population at day 15 pi. Results represent the mean ± SEM of two independent experiments with three mice each. Data were evaluated by analysis of variance for each cell type separately and versus blood (*P <0.05 and **P <0.01) (Dunnet post hoc test). Electron microscopy of non-infected (B) and infected (C) blood CD71^hi cells obtained after sorting showed early reticulocytes containing different organelles. Mitochondria (m), vesicles (v) and parasite (p).
