Comparison of aqueous grain dusts, cotton dusts, and mold extracts by crossed immunoelectrophoretic techniques.
To evaluate the possibility that an immune response is involved in the pathogenesis of grain dust or cotton dust induced respiratory disease, 1 grain dust extract (A) was compared with 4 similar grain dust extracts, a cotton dust extract, and a mixture of fungal preparations, using crossed immunoelectrophoretic techniques and rabbit anti-A sera. All extracts demonstrated a significant number of shared antigenic determinants. These data suggest that grain and cotton dust may induce disease via a common pathogenic mechanism and putative agent(s).
