title: Humoral immunity in disseminated Aspergillus terreus infection in the dog.
abstract: Aspects of humoral immunity were studied in 17 dogs with disseminated aspergillosis (16 cases Aspergillus terreus, 1 case Aspergillus flavipes). All dogs had markedly raised serum IgG levels by single radial immunodiffusion (range 1500-6000 mg dl-1). Despite this, serum antibody to A. terreus was demonstrated in only 7/16 cases by agar gel diffusion, 9/16 cases by counter immunoelectrophoresis, 10/16 by ELISA and 11/16 by an indirect immunofluorescence assay. Serum antibody was also detected in 2/5 clinically normal relatives of 2 cases, indicating previous exposure or subclinical infection.
