Detection of gp43 antigen in bronchoalveolar lavage from patients with pulmonary PCM and in cerebrospinal fluid from patients with neuroparacoccidioidomycosis by inh-ELISA. Groups studied: 1, bronchoalveolar lavage fluid (n = 13); 2, bronchoalveolar lavage fluid of patients with no fungal pulmonary disease (n = 10) (controls); 3, cerebrospinal fluid from neuroparacoccidioidomycosis patients (n = 14); 4, cerebrospinal fluid from patients with no fungal disease (n = 6); 5, serum from patients with neuroparacoccidioidomycosis (n = 11). Bars represent the average antigen concentration for each group. The cutoff point was 0.23 μg/ml.
