Figure 2.

Progression of the blood-stage infection in mice injected with P. yoelii parasitized RBCs. The triangles represent parasitemia values measured by GFP-based flow cytometric detection; the squares represent parasitemia values determined by microscopy and the circles display the RMOD signal. The empty squares and triangles show samples declared negative either by microscopy after counting 10,000 red blood cells, or by flow cytometry. Each symbol and error bar represents the average and standard deviation of values measured on blood samples from n = 4 mice. The continuous black line represents the average of the RMOD values of ~20 uninfected control samples. The dashed black lines indicate the detection limit of RMOD defined as the average plus two times the standard deviation of the uninfected values.
