Hemoglobin rates, hematocrit and glucose-6-phosphate dehydrogenase (G6PD) and glutathione reductase activities were measured in 38 patients with paracoccidioidomycosis treated with ketoconazole or sulfadoxin, and in 13 normal individuals. Ketoconazole-treated patients showed reduced G6PD and
The authors evaluated the isoniazid acetylating phenotype and measured hematocrit, hemoglobin, glucose-6-phosphate dehydrogenase and glutathione reductase activities plus serum sulfadoxin levels in 39 patients with paracoccidioidomycosis (33 males and 6 females) aged 17 to 58 years. Twenty one
A cDNA coding for a new member of the 70-kDa heat shock proteins (HSP70) family from the dimorphic and pathogenic fungus, Paracoccidioides brasiliensis, was cloned and characterized. The cDNA-deduced sequence coded for 655 amino acid residues and showed 95% identity to a previously described P.
Paracoccidioidomycosis (PCM), caused by the dimorphic fungus Paracoccidioides brasiliensis, is a disseminated, systemic disorder that involves the lungs and other organs. The ability of the pathogen to interact with host components, including extracellular matrix (ECM) proteins, is essential to
An antigen of Paracoccidioides brasiliensis (Pb) was gel isolated and characterized. Endoproteinase Lys-C-digested peptides of the purified protein, which presented a molecular mass of 29 kDa and pI of 5.8, were subjected to sequence analysis of their amino acids. Searches at databases comparing the
A cDNA coding for an antigenic protein (rPb27) from the pathogenic fungus Paracoccidioides brasiliensis was cloned and its protective activity was determined against paracoccidioidomycosis (PCM). The cDNA sequence contained an open reading frame (ORF) of 660 base pairs encoding a protein of 219
Paracoccidioides brasiliensis is a well-characterized pathogen of humans. To identify proteins involved in the fungus-host interaction, P. brasiliensis yeast proteins were separated by liquid isoelectric focusing, and fractions were subjected to sodium dodecyl sulfate-polyacrylamide gel
gp43 is the major diagnostic antigen of Paracoccidioides brasiliensis, the agent of paracoccidioidomycosis (PCM) in humans. In the present study, cDNA of the gp43 gene (PbGP43) was obtained by reverse transcriptase PCR, inserted into a pGEX vector in frame with the glutathione S-transferase (GST)
A gene encoding the heat shock protein (HSP) 60 from Paracoccidioides brasiliensis (Pb) was cloned and characterized. The hsp60 gene is composed of three exons divided by two introns. Structural analysis of the promoter detected canonical sequences characteristic of regulatory regions from
