Eighteen (3.6%) sera from the tuberculosis patients were positive in the immunodiffusion test: 8 against paracoccidioidin, 7 against aspergillin, 2 against histoplasmin and 1 against sporotrichin. Seven of the eight tuberculosis patients with precipitin antibodies to paracoccidioidin were female. Antibodies to histoplasmin, aspergillin and sporotrichin were not detected in any of the sera from the asymptomatic individuals.
