Immunochemical study of a Paracoccidioides brasiliensis polysaccharide-like antigen
(1995-12-01)
The polysaccharide antigen from P. brasiliensis has been largely employed in serologic tests, as well as in skin tests, to evaluate cellular immunity. SDS-PAGE analysis of this antigen has revealed a variability in the ...
Specific components found in circulating immune complexes (CIC) in paracoccidioidomycosis
(1996-10-19)
Circulating immune complexes (CIC) from 15 paracoccidioidomycosis (PCM) patient sera and from 20 healthy control sera were analysed. After CIC precipitation, solubilization and acid treatment, only a little reactivity to ...
The effect of Ketoconazole on experimental paracoccidioidomycosis in the Syrian hamster: immunological and histopathological study
(1984-12-01)
The effect of Ketoconazole (KTZ) on the hamster experimental intratesticular paracoccidioidomycosis was studied employing different treatment schedules. KTZ long course treatment beginning at an early stage of the infection ...
Serology of paracoccidioidomycosis. II. Correlation between class-specific antibodies and clinical forms of the disease
(1984-12-01)
Untreated and previously treated patients with paracoccidioidomycosis were studied for: (i) serum levels of total IgG, IgM and IgA immunoglobulins, by radial immunodiffusion and Paracoccidioides brasiliensis (Pb) antibodies, ...
Sputum cytology in the diagnosis of pulmonary paracoccidioidomycosis
(1991-06-01)
The presence of Paracoccidioides brasiliensis was determined in sputum samples from 50 patients with paracoccidioidomycosis using four different techniques: (a) cell-block preparations stained with silver methenamine, (b) ...
Paracoccidioidomicose: estudo radiológico e pulmonar de 58 casos
(1991-07-01)
Spirometric and haemogasimetric tests were performed in 52 patients with unifocal and multifocal progressive Paracoccidioidomycosis pulmonary diseases, in 5 patients with juvenile and 1 female internal genital forms. The ...
Pulmonary paracoccidioidomycosis in immunized mice
(1992-07-01)
Paracoccidioidomycosis was induced in immunized (IM) and non-immunized (NI) mice. The histopathology, the number of fungi in the lungs, the cellular (footpad test - FPT and macrophage inhibition factor assay - MIF) and ...
Paracoccidioides brasiliensis antigen batches from the same isolate show immunological and biochemical differences
(1996-12-01)
We investigated the occurrence of antigenic and biochemical variability among Paracoccidioides brasiliensis antigen batches prepared according to the same protocol. Initially (experiment 1), we analyzed two antigen lots ...
Detection of the 43,000-molecular-weight glycoprotein in sera of patients with paracoccidioidomycosis
(1989-12-09)
The 43,000-molecular-weight (43K) soluble glycoprotein was detected in sera of patients with paracoccidioidomycosis by the immunoblot technique by using as the probe rabbit monospecific antisera to this fraction. The 43K ...
