Quantitation of pulmonary fungal burden in Paracoccidioides brasiliensis-infected mice by real-time PCR

Revista do Instituto de Medicina Tropical de São Paulo, 2018
Although colony-forming unit (CFU) counting is widely used to quantify fungal load in tissue from animal experimentally infected with Paracoccidioides brasiliensis, several technical disadvantages have been described.

Immunity and hypersensitivity to gp43 antigen in susceptible and resistant mice infected with Paracoccidioides brasiliensis

, 2003
Pathogenic mechanisms underlying paracoccidioidomycosis are still poorly understood. A well-established murine model of resistance (mouse lineage A/Sn) and susceptibility (lineage B10.A) to P brasiliensis pulmonary infection was here employed to compare ...

Antifungal and antitumor models of bioactive protective peptides

Anais da Academia Brasileira de Ciências, 2009
Peptides are remarkably reactive molecules produced by a great variety of species and able to display a number of functions in uni-and multicellular organisms as mediators, agonists and regulating substances. Some of them exert cytotoxic effects on cells

Anti-gp43 antibody detection.

, 2019
The levels of anti-gp43 antibody were determined in sera from B10.A and BALB/c mice by ELISA. Groups of five mice each were inoculated intratracheally with 106 P. brasiliensis yeast cells. Serum samples were obtained by tail vein bleeding at the 30th day

Recombinant 60-kDa heat shock protein from Paracoccidioides brasiliensis: is it a good antigen for serological diagnosis of paracoccidioidomycosis?

Brazilian Journal of Medical and Biological Research
Paracoccidioides brasiliensis and P. lutzii are fungi that cause paracoccidioidomycosis (PCM), the most prevalent systemic mycosis in South America. For serological diagnosis, although 43-kDa glycoprotein (gp43) is regarded as highly specific for PCM ...

Characterization of a Paracoccidioides spp. strain from southeastern Brazil genotyped as Paracoccidioides restrepiensis (PS3) and review of this phylogenetic species

Genetics and Molecular Biology
Phylogenetic species of Paracoccidioides brasiliensis complex (S1a and S1b, PS2, PS3, and PS4) and Paracoccidioides lutzii are agents of paracoccidioidomycosis, an endemic fungal disease in Latin America. P. restrepiensis (PS3 genotype) was classified as
