Analysis of IgE, IgA and IgG antibodies directed against Candida albicans antigens in 28 asthmatic children was performed with immunoblotting after SDS-PAGE. Analysis with the purified cytoplasmic protein fraction revealed a major protein allergen with an MW of 46 kD. In addition to the major allergen, 15 other antigenic bands with molecular weights between 16 and 135 kD bound IgE. Ten of 13 anti-C. albicans IgE-positive children had IgE towards the 46 kD major allergen. None of the subjects in the study group or in the non-atopic controls had IgA or IgG antibodies towards this protein. Analysis of the crude surface extract showed that mannan, a carbohydrate, was an intermediate allergen contrary to being the major antigen in IgA and IgG antibody responses.
