(A) Chronic P. chabaudi parasitemia in J_H^−/− mice injected i.p with 1 × 10⁶ parasitized erythrocytes. (B) The number of splenic CD3⁺ CD4⁺ and CD3⁺ TCRγδ⁺ cells was assessed by flow cytometry at weeks 0, 3, 6, and 12 p.i. during the course of P. chabaudi infection in groups (n = 3) of mice. The number of mice available for assessment of parasitemia was initially 12 and then declined by 3 as splenocytes were obtained from groups of mice for the flow cytometric analysis. Data represent the mean (±SD) for each time point.
