We report the case of a young man who developed severe asthma a few months after starting work in a factory producing a single type of mushroom: Pleurotus cornucopiae (a basidiomycete). Immunological investigations, performed with material recovered from the filtering devices of the mushroom's bed, led to demonstration of specific IgE and IgG against spore extracts and to isolation of one discriminant antigen (molecular weight: 10.5 kd). Current data concerning the underestimated role of the basidiomycetes in allergic asthma are reviewed.

D011124 Polyporaceae A family of bracket fungi, order POLYPORALES, living in decaying plant matter and timber.
D011852 Radioallergosorbent Test An in vitro allergen radioimmunoassay in which allergens are coupled to an immunosorbent. The coupled allergens bind the IgE in the sera of patients which in turn binds radioisotope-labeled anti-IMMUNOGLOBULIN E antibodies. Radioimmunosorbent Assay of Allergens,Allergens Radioimmunosorbent Assay,Allergens Radioimmunosorbent Assays,Radioallergosorbent Tests,Test, Radioallergosorbent,Tests, Radioallergosorbent
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
