FIG 1.

Transient loss of serum bactericidal immunity to S. Typhimurium during current and convalescent P. falciparum infection. Serum bactericidal activity was reported as the log10 change in S. Typhimurium CFU counts per milliliter from the baseline, and this was plotted as indicated during malaria and in controls. (A) Red bars represent the median, and statistical differences were determined by the Mann-Whitney U test. (B) Serum bactericidal activity measurements for each subject during current and convalescent malaria are linked by solid gray lines.
