title: Immunoreactivity of antigen extracts of Aspergillus fumigatus isolated from different sources.
abstract: Allergic bronchopulmonary aspergillosis (ABPA) is the result of hypersensitivity to Aspergillus antigens in patients with long-standing atopic asthma. In the present study mycelial and culture filtrate antigens from Aspergillus fumigatus cultures isolated from diverse sources were tested against sera of 10 ABPA patients and 10 control individuals by an ELISA methodology. The results indicate higher antibody reactivity against both antigens in the sera of ABPA patients, while culture filtrate antigens also gave non-specific reactivity with control sera. Mycelial extracts, in general, were useful in the diagnosis of ABPA.
