Abstract

Background. Antibodies targeting blood stage antigens are important in protection against malaria, but the principle targets remain unclear. Erythrocyte-binding antigens (EBAs) are important erythrocyte invasion ligands used by merozoites and may be targets of protective immunity, but there are limited data examining their potential importance. Methods. We examined antibodies among 206 Papua New Guinean children who were treated with antimalarials at enrolment and observed prospectively for 6 months for reinfection and malaria. Immunoglobulin (Ig) G, IgG subclasses, and IgM to different regions of EBA175, EBA140, and EBA181 expressed as recombinant proteins were assessed in comparison with s..
