Abstract
Aqueous extracts of Fusarium solani and other members of the Fungi Imperfecti were evaluated for the presence of common antigenic allergenic determinants using skin-prick testing, radio-allergo-sorbent test (RAST) inhibition, and immunoelectrophoretic methods. Prevalence of skin reactivity in forty-four atopic individuals, tested with commercially available fungal extracts, ranged from 27.3% for Alternaria tenuis to 6.8% for Penicillium notatum. No specific patterns of reactivity emerged from statistical analyses of skin test data. In contrast, RAST inhibition demonstrated common allergenic determinants. P. notatum and Aspergillus glaucus inhibited F. solani RAST by 79% and 84%, respectively. This was supported by crossed line immunoelectrophoresis; both P. notatum and A. glaucus had antigenic determinants in common with F. solani. Collectively, these studies suggest that F. solani, P. notatum, and A. glaucus have several common antigenic/allergenic determinants.
