FIG. 2.

Prevalence and titer of antibodies against different regions of MSP6 in hyperimmune sera (n = 30) from Ivory Coast. Antibody reactivity was considered to be positive if the ratio of the mean OD of the test sera to the mean OD of the control sera + 3 × the standard deviation of the control sera was ≥1. The figure represents antibody titers, expressed as a ratio for each serum, and the dotted line represents the baseline of a ratio equal to 1. The horizontal bars represent the arithmetic mean level of each isotype for positive sera. The table shows the prevalence of sera positive for total IgG to different regions of MSP6.
