Molecular detection of Paracoccidioides in soil from an urban area of southern Brazil

Revista da Sociedade Brasileira de Medicina Tropical, 2020
INTRODUCTION: Previous studies that detected Paracoccidioides spp. DNA in soil taken from rural areas have shown this to be a valuable tool for ecological and epidemiological studies. This study reports the detection of Paracoccidioides spp. DNA in soil

Proteomic Analysis of Paracoccidioides brasiliensis During Infection of Alveolar Macrophages Primed or Not by Interferon-Gamma

Frontiers in Microbiology, 2019
Although members of the Paracoccidioides complex are not obligate intracellular pathogens, they present the ability to survive and multiply inside epithelial cells and phagocytes of mammals, which may favor the spread of the fungus in host tissues ...

Paracoccidioides Species Circulating in the Endemic Area of Rio de Janeiro, Brazil: Updates into Their Genetic Diversity

Journal of Fungi
Paracoccidiodomycosis (PCM) is the most important systemic mycosis in Brazil, and is usually associated with rural work. PCM is caused by inhalation of infective propagules of thermodimorphic fungi from the genus Paracoccidioides.

Extracellular vesicles from Paracoccidioides brasiliensis induced M1 polarization in vitro

Scientific Reports, 2016
Extracellular vesicles (EVs) released by eukaryotes, archaea, and bacteria contain proteins, lipids, polysaccharides, and other molecules. The cargo analysis of EVs shows that they contain virulence factors suggesting a role in the pathogenesis of ...

Primers for Clinical Detection of Paracoccidioides brasiliensis [PDF]

Journal of Clinical Microbiology, 2005
ABSTRACT From a 0.72-kb fragment universally generated in Paracoccidioides brasiliensis strains, primers were designed and tested on genomic DNA of this and other pathogenic fungi. They were specific and highly sensitive for P. brasiliensis DNA.

Fungal DNA‐barcoding on a chip: Magnetoresistive biosensors for yeast infection diagnosis

VIEW, EarlyView.
The development of a fungal pathogen identification chip is herein demonstrated. Hybridization dynamics were tested against 58 species in silico and 4 species on chip. 95% accuracy, 91% sensitivity, 98% specificity and femtomolar limit of detection were achieved. Future perspectives include the integration of sample pre‐treatment modules.

Paracoccidioides spp.: the structural characterization of extracellular matrix, expression of glucan synthesis and associated genes and adhesins during biofilm formation

Frontiers in Microbiology
The genus Paracoccidioides includes Paracoccidioides lutzii and the Paracoccidioides brasiliensis complex, which comprises four phylogenetic species. A key feature distinguishing planktonic growth from biofilm is the presence of a 3D extracellular matrix

NLRP3 Inflammasome Activation by Paracoccidioides brasiliensis

PLoS Neglected Tropical Diseases, 2013
Paracoccidioides brasiliensis is the etiologic agent of paracoccidioidomycosis (PCM), the most prevalent systemic mycosis that is geographically confined to Latin America. The pro-inflammatory cytokine IL-1β that is mainly derived from the activation of the cytoplasmic multiprotein complex inflammasome is an essential host factor against opportunistic ...

Silica Nanoparticles as Multifunctional Platforms for Vaccine Delivery and Immune Modulation in Infectious Diseases

Advanced NanoBiomed Research, Volume 5, Issue 12, December 2025.
Overview of the use of silica nanoparticles in vaccines against pathogens. Different kinds of vaccines against infectious diseases are currently using solid or mesoporous silica nanoparticles in their formulation. Silica microparticles and nanoparticles (SiNPs) have been studied as vehicles for vaccines.
