Immunoglobulin allotypes in symptomatic and asymptomatic pigeon breeders.

Comparison of immunoglobulin allotypes were studied in a group of patients with pigeon breeder's disease and in similarly exposed by asymptomatic individuals. The study revealed that the disease is not correlated with immunoglobulin allotypes. Furthermore, the phenotype Gm(a;g) was not associated with high levels of serum antibodies to pigeon antigens.
