Excretory-secretory antigenic components of Paragonimus heterotremus recognized by infected human sera

Antigenic components of Paragonimus heterotremus metabolic products were revealed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblot analysis of sera from patients with P. heterotremus infection, from patients with other illnesses, and from healthy adults. By SDS-PAGE, it was found that the metabolic products comprised more than eight major polypeptides. Immunoblot analysis revealed 11 components which were...
