Fig. 3. : evaluation of recrudescence after treatment with antimalarial drugs. Mice were infected with green fluorescent protein-expressing Plasmodium berghei (PbGFP) and treated with artesunate (A), chloroquine (B) or primaquine (C) at day 3 post-infection and parasitaemia was evaluated up to 96 h after treatment. Parasitaemia was evaluated by microscopy (black bars) and cytometry (hatched bars). The results are expressed as the mean ± standard deviaton from at least six animals per group in two different experiments. Statistically significant differences compared to the group evaluated by microscopy (p < 0.05) are indicated by an asterisk.
