Pigeon IgA: a major antigen in pigeon breeder's disease.
Pigeon IgA has been isolated from crop-milk and an antiserum was produced. Extracts of the dust in pigeon coops contained detectable amounts of pigeon IgA, but not IgG. The sera of patients with pigeon breeder's disease contained precipitating antibody against pigeon IgA.
