title: Chagas' disease: humoral response to subcellular fraction of Trypanosoma cruzi in symptomatic and asymptomatic patients.
abstract: The capacity of antibodies in serum from individuals with chronic Chagas' disease to react with antigens in different subcellular fractions of Trypanosoma cruzi varied according to the clinical status of the patients. Antibodies in serum of asymptomatic patients were directed mostly against antigens in the citosol of the parasite, whereas in overtly cardiopathic patients antibodies were directed mostly against antigens in the microsomal fractions.
