Increase in blood parasitemia level following exposure to sand fly bites. A, Parasite loads in whole blood specimens obtained from hamsters infected with Leishmania donovani strain Mongi as determined by titration culture using blood specimens obtained before and after sand fly exposure. Data are log parasite counts per milliliter of blood, with geometric means denote by bars (data are for 8 mice). B, Parasite loads in whole blood specimens as determined by quantitative polymerase chain reaction (qPCR), using blood obtained before and after sand fly exposure. Data are log parasite counts per milliliter of blood, with geometric means denoted by bars.
