title: Characterization of antigens from Aspergillus fumigatus. III. Comparison of antigenic relationships of clinically important aspergilli.
abstract: Antigenic relationships between strains of Aspergillus fumigatus, Aspergillus fumigatus var. elipticus, Aspergillus phialiseptus, Aspergillus flavus, and Aspergillus niger were analyzed by fused rocket immunoelectrophoresis and by skin tests. Seventy-three to 89 % of the numbers of antigens detected between strains and species of the A. fumigatus series were shared. The degree of sharing between antigens of A. flavus, A. fumigatus series, and A. niger was much lower and ranged from 19 to 35 %. In reciprocal skin tests in sensitized guinea pigs, similar relationships were shown. Three fractions of A. fumigatus extract proved to be markedly specific for this species. Cross reactivity was associated primarily with carbohydrate and glycoprotein fractions.
