Figure 1: A comparison of the total IgG, IgG1 and IgG3 levels to CSP, AMA1 and MSP119 in plasma. The samples were from three groups: Fulani (black bar), Mandinka (light gray bar) and Wolof (dark gray). Antibodies titres (pg/ml) were measured by ELISA. The total anti-CSP IgG concentration was higher among Fulani and Wolof compared to Mandinka samples, although there was no significant difference in the levels of IgG1 and IgG3. The concentrations of anti-AMA1 total IgG, IgG1 and IgG3 were not significantly different between the three groups. Higher concentrations of both anti-MSP119 total IgG and IgG1 were observed for the Fulani compared to the Mandinka and Wolof samples.
