TABLE 1.

Patterns of IgG antibody recognition of four MSP-2 peptides (FC27, S20, 3D7, and FUP/CP), as determined by enzyme-linked immunosorbent assay, in 54 adult malaria patients from Brazilaa

TABLE 1.
  • a Thirteen patients were infected with genetically heterogeneous parasite populations expressing both MSP-2 types FC27 and IC1. Black boxes represent strong IgG antibody responses (reactivity indices ≥ 5), and open boxes indicate that no IgG antibodies were detected (reactivity indices < 1). Light- and dark-shaded boxes represent reactivity indices between 1 and 2.4 and between 2.5 and 4.9, respectively. Reactivity indices were calculated as the ratio of absorbance value obtained with test sera and negative control sera assayed on the same microplate (see the text for details). Ages are given in years.
