FIG. 1.

Evolution of P. falciparum parasitemia in seven untreated mice. Mice were inoculated i.p. with 1 ml of highly synchronized cultures of P. falciparum at the ring stage on day 0. After infection, mice received normal RBC every 3 to 4 days. Parasitemia in mice was expressed as the percentage of P. falciparum-huRBC in the total RBC observed in thin smears. The data shown are from the first day of detectable parasitemia up to the day the mice were used for other malaria studies.
