Ravuconazole-resistant clones delayed parasitemia peak in vivo when compared to the sensitive clones. Parasitemia (A) and percent survival (B) of animals infected with strain Y and H10-S, H10-LT, H10-R-NP and H10-R clones. Animals was infected with 10,000 forms from each Y strain and H10–S, H10-LT, H10-R, H10-R-NP clones. Peripheral blood was collected from infected animals and parasitaemia determined by optical microscopy until day 15 post infection. Survival followed each group until day 30 post infection.
