FIG. 1.

Cytophilic IgG subclasses responses to the C-terminal portion of the six MSP3 antigens in serum samples of individuals of all age groups (n = 76; range, 0.9 to 80.4 years; mean age, 14.4 years) from Dielmo, Senegal. To calculate the prevalence values, antibody responses were considered positive when the net OD value of each serum sample was greater than the mean OD + 3 SD of control serum samples. The mean of net OD values represents the mean responses of the positive serum samples. Bars indicate the standard errors of the mean.
