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...

Epidemiology of paracoccidioidomycosis in Venezuela: a retrospective study from 1954 to 2019

Mem. Inst. Oswaldo Cruz; 116 (), 2021
BACKGROUND Paracoccidioidomycosis (PCM) is a systemic mycosis endemic to Latin America. Etiological agents are Paracoccidioides species that diverge phylogenetically throughout South America. OBJECTIVES This study aimed to document the epidemiology of PCM in Venezuela. METHODS We have performed a re...

Paracoccidioides brasiliensis habitat: far beyond armadillo burrows?

Mem. Inst. Oswaldo Cruz; 115 (), 2020
Paracoccidioides spp. isolation from environmental samples is rare and hardly reproducible. Molecular techniques have facilitated the fungal detection. However, it can be still difficult. Some strategies to enhance the capacity of DNA detection have been adopted, including the analysis of soil samples be...

Fatal septic shock caused by Paracoccidioides brasiliensis phylogenetic species S1 in a young immunocompetent patient: a case report

Abstract The authors report the first case of fatal septic shock, a rare clinical presentation of paracoccidioidomycosis (PCM) caused by Paracoccidioides brasiliensis S1. We also provide an immunological evaluation of the patient. Severe clinical signs such as organ dysfunction and digital gangrene occur...

Use of fluorescent oligonucleotide probes for differentiation between Paracoccidioides brasiliensis and Paracoccidioides lutzii in yeast and mycelial phase

Mem. Inst. Oswaldo Cruz; 112 (2), 2017
BACKGROUND Fluorescence in situ hybridisation (FISH) associated with Tyramide Signal Amplification (TSA) using oligonucleotides labeled with non-radioactive fluorophores is a promising technique for detection and differentiation of fungal species in environmental or clinical samples, being suitable for ...

Diagnóstico molecular de paracoccidioidomicose associada à tuberculose em amostras de escarro
Paracoccidioidomycosis molecular diagnosis associated with tuberculosis in sputum samples

Clin. biomed. res; 36 (3), 2016
Introdução: A paracoccidioidomicose (PCM) é uma micose sistêmica endêmica causada pelo fungo Paracoccidioides spp. O objetivo deste estudo foi determinar a associação entre tuberculose (TB) e PCM em pacientes com exame micológico negativo. Métodos: Estudo prospectivo de diagnóstico molecular de...
