A family was recently studied in which two brothers with identical HLA serotypes had allergic bronchopulmonary aspergillosis. One of the two had a normal bronchogram. A field investigation of the family residence showed that a barn was the probable source of the organism causing disease in these patients. Immunologic characterization of the family members showed a broad spectrum of response to the environmental exposure.
