Patterns of total IgG responses to four PfMSP-1
variants in Iranian individuals infected with P . falciparum isolate. Infected PfMSP-119 variant forms in each patient were detected by sequencing analysis. Ages are given in years. Antibody reactivity of each sample is measured by ELISA. Cut-off values are 0.2, 0.3, 0.37 and 0.26 for IgG responses to E/TSG/L, E/TSR/L, E/KNG/F, and Q/KNG/L variants, respectively. The OD means values for IgG responses have been divided into the following groups: OD > 2: High-positive antibody responses. 1 > OD > 2: Medium-positive responses. OD < 1: Low-positive responses. OD < Cut-off: Negative.
