Parasitemia of unimmunized infected mice. Groups of C57BL/6J and A/J mice were challenged intravenously with 104 P. berghei ANKA-parasitized erythrocytes. Percentages of erythrocytes with parasites were determined by examination of thin blood smears from individual mice taken at 2- to 4-day intervals until death. The groups are C57BL/6J mice (n = 10), which are susceptible to CM (A), and A/J mice (n = 10), which are resistant to CM (B).
