Diagnóstico micológico de paracoccidioidomicosis en un hospital de área no endémica: metodología clásica y molecular

Biomédica (Bogotá); 43 (Supl. 1), 2023
Introducción. La paracoccidioidomicosis es una micosis sistémica y endémica en Latinoamérica. El cambio climático y el movimiento migratorio del huésped enfatizan la necesidad de optimizar el diagnóstico de esta infección. Objetivo. Evaluar la implementación de la detección de ADN de Paracoccid...

Hiperplasia pseudoepiteliomatosa: carcinoma escamocelular versus paracoccidioidomicosis oral, un caso con mirada dermatológica

Biomédica (Bogotá); 43 (Supl. 1), 2023
La paracoccidioidomicosis es una micosis sistémica endémica en Latinoamérica. La presentación más frecuente compromete crónicamente los pulmones, la piel y las mucosas. Al inicio, este paciente presentó, por varios años, una lesión única en la mucosa oral que, en ausencia de otros síntomas, se...

Fast and cost-effective protocol to produce Paracoccidioides spp. antigens

Biomédica (Bogotá); 43 (Supl. 1), 2023
Introduction. The existing methods for Paracoccidioides spp. antigen production are problematic in terms of standardization, specificity, stability, repeatability, and reproducibility. Objective. To optimize the methodology for Paracoccidioides spp. antigen production and evaluate its applicability in pa...

Multifocal Pseudotumorous Form of Neuroparacoccidioidomycosis in an Immunocompetent Patient: A Clinicopathological Review Based on a Case Report

Arq. bras. neurocir; 40 (2), 2021
Neuroparacoccidiodimycosis (NPDM) is an uncommon granulomatous disease, which more frequently affects immunocompromised male patients over 30 years of age in the course of chronic lung disease. Paracoccidioides brasiliensis (PB) is an endemic fungus in Brazil, and grows as thick-walled yeast (with round ...

Disseminated paracoccidioidomycosis in a liver transplant patient

An. bras. dermatol; 96 (3), 2021
Abstract Paracoccidioidomycosis is an endemic systemic mycosis caused by Paracoccidioides brasiliensis complex and P. lutzii. It is a rare disease in non-HIV-induced immunosuppressed individuals. In organ transplant recipients, it is more frequently associated with immunosuppression after kidney transpla...

Gene expression of Paracoccidioides virulence factors after interaction with macrophages and fibroblasts

Mem. Inst. Oswaldo Cruz; 116 (), 2021
BACKGROUND Paracoccidioidomycosis (PCM) is a systemic mycosis with high prevalence in Latin America that is caused by thermodimorphic fungal species of the Paracoccidioides genus. OBJECTIVES In this study, we used quantitative polymerase chain reaction (qPCR) to investigate the expression of genes rel...

Braz. j. infect. dis; 25 (4), 2021
ABSTRACT Background: Paracoccidioidomycosis is a systemic mycosis considered endemic and limited to Latin America with the majority of registered cases originating from Brazil. The purpose of this paper was to report a case of a female patient with paracoccidioidomycosis mimicking inflammatory bowel dis...

Serological diagnosis of paracoccidioidomycosis using a Paracoccidioides spp. comercial antigen and the counterimmunoelectrophoresis method

Braz. j. infect. dis; 25 (5), 2021
ABSTRACT Purpose: In-house Paracoccidioides spp. antigens are commonly used in the serological diagnosis of paracoccidioidomycosis (PCM). The sensitivity and specificity of a commercial Paracoccidioides spp. antigen was assessed for PCM serological testing. Method: Counterimmunoelectrophoresis and doub...
