Plasmodium falciparum population dynamics in an asymptomatic 9 year old child in 6-hourly samples over 5 days. Parasite densities and morphologic stages determined by microscopy of Giemsa-stained thin and thick smears. Parasite populations were characterized by PCR based genotyping of msp1 and msp2. PCR products of the same base pair length within the respective allelic types were defined as the same alleles and schematically illustrated as boxes with the same patterns and colours. The respective allelic types of msp1 and msp2 are illustrated by different colours. *not done/missing sample
