IgG1 and IgG4 Antibody Responses to the Anopheles gambiae Salivary Protein gSG6 in the Sympatric Ethnic Groups Mossi and Fulani in a Malaria Hyperhendemic Area of Burkina Faso
Figure 1
Seasonal variation of the gSG6-specific IgG1 and IgG4 antibody titers in the sympatric ethnic groups Mossi and Fulani.
Scatter plots reporting IgG1 (left panel) and IgG4 (right panel) antibody titers among gSG6 IgG responders of the Mossi and Fulani ethnic groups in the three different surveys. C, unexposed controls. Bars indicate median values. Number of individuals analyzed (n) and average age in years ±95% CI were as follows. August: Mossi n = 60 (22.0±4.5), Fulani n = 63 (16.1±3.9); October: Mossi n = 56 (13.0±3.4), Fulani n = 30 (21.2±7.0); March: Mossi n = 32 (15.3±5.1), Fulani n = 29 (11.6±4.2); Controls n = 44 (33.1±7.1). P values determined according to the Kruskal-Wallis test. Pairwise comparisons refer to the Mann-Whitney U test (*, 0.01<p<0.05; **, 0.001<p<0.01; ***, p<0.001). Note that one (left panel) and twenty-six (right panel) data points are outside the axis limits.
