HEMAGGLUTINATION-INHIBITING IMMUNOGLOBULIN A ANTIBODY IN THE SERUM OF PATIENTS WITH DENGUE HEMORRHAGIC FEVER

Abstract
In convalescent-phase sera of patients with dengue hemorrhagic fever, hemagglutination-inhibiting (HI) antibody of immunoglobulin (Ig) A class, in both monomeric and oligomeric forms, was detected. It was found to be less type-specific than IgM HI, and as broadly cross-reacting as IgG HI antibodies.
