Cross-reactive antibodies against Plasmodium falciparum antigens. (a) IgM against P. falciparum schizont extract, (b) IgM against P. falciparum Merozoite Surface Protein (MSP)-1₁₉, (c) IgG against P. falciparum schizont extract, and (d) IgG against P. falciparum MSP-1₁₉. The solid line represents the concentration of IgM, or the titer of IgG as compared to the hyper-immune pooled serum (titer = 1). The broken line denotes the upper 95% confidence limit obtained from the baseline, while the mean and confidence interval in the control subjects are denoted as the vertical bar overlapping Y axis.
