Fig. 4From: Immunogenicity of glycosylphosphatidylinositol-anchored micronemal antigen in natural Plasmodium vivax exposureIgG isotype responses to the PvGAMA antigen. The prevalence of the IgG isotype response to PvGAMA (a) and PvDBPII (b) in patients with acute P. vivax infection (n = 29) compared with healthy controls (n = 18). The stability of IgG1 and IgG3 antibody responses to PvGAMA was shown from cross-sectional study (c) and the monitoring in individuals (d) of acute infected patients (n = 5). Each symbol represents the IgG1, IgG2, IgG3 and IgG4 titre of one individual. The solid line shows the median antibody titre in each group. The dotted line indicates the cut-off valuesBack to article page
