IFA images of methanol-fixed slides of the field isolate Gb337 in (A) early ring, (B) ring, (C) trophozoite, (D) schizont and (E) gametocyte stages visualized using anti-STEVOR (anti-PFL2610w) antibody. The localization of STEVOR proteins to the merozoite surface and the rhoptries together with its prevalence as a released component in the invading merozoite suggest a role of these antigens in adhesion and/or immune evasion in the erythrocyte invasion process.
