Abstract:
We report on a patient with asthma induced by occupational exposure to alpha-amylase derived from Aspergillus oryzae, which is a component of bread additives. A type I hypersensitivity to this enzyme was demonstrated by means of skin test, immunoassay for specific IgE, and immediate bronchial provocation test response to an alpha-amylase extract.
