Immediate Type Hypersensitivity to Common Moulds Comparison of Different Diagnostic Materials

Abstract
Extracts of 5 common [human respiratory-allergy causing] atmospheric molds (Alternaria, Aspergillus, Cladosporium, Mucor and Penicillium) obtained from different manufacturers were compared by skin prick testing and, partly, with the radioallergosorbent test. Considerable differences were found between the extracts with respect to positive tests found in mold-allergic individuals and controls. A purified allergen preparation of Cladosporium herbarum was superior to the crude allergen extracts. The allergen contents of the extract differed both with respect to total allergenic potency and to allergenic composition.
