Differential distribution patterns of Fonsecaea agents of chromoblastomycosis, exemplified by the first case due to F. monophora from Argentina

Medical Mycology Case Reports, 2018
Chromoblastomycosis is a mutilating infection of the skin and subcutaneous tissues caused by melanized fungi belonging to the order Chaetothyriales. Proven cases of the main agent, Fonsecaea pedrosoi are mainly limited to (sub)tropical, humid climates of

Phosphatase activity on the cell wall ofFonsecaeapedrosoi [PDF]

Medical Mycology, 2003
The activity of a phosphatase was characterized in intact mycelial forms of Fonsecaea pedrosoi, a pathogenic fungus that causes chromoblastomycosis. At pH 5.5, this fungus hydrolyzed p-nitrophenylphosphate (p-NPP) to p-nitrophenol (p-NP) at a rate of 12.78 +/- 0.53 nmol p-NP per h per mg hyphal dry weight.

A screening of the MMV Pathogen Box® reveals new potential antifungal drugs against the etiologic agents of chromoblastomycosis.

PLoS ONE, 2020
Chromoblastomycosis (CBM) is a chronic subcutaneous mycosis caused by traumatic implantation of many species of black fungi. Due to the refractoriness of some cases and common recurrence of CBM, a more effective and less time-consuming treatment is ...

Molecular epidemiology of Fonsecaea pedrosoi using mitochondrial DNA analysis [PDF]

Medical Mycology, 1999
Restriction fragment length polymorphism (RFLP) of mitochondrial DNA (mtDNA) from 49 clinical Fonsecaea pedrosoi isolates (18 isolates from Japan, 17 from Madagascar, 7 from Argentina, 5 from Venezuela, 1 from Costa Rica and 1 unknown) was studied. The 49 isolates were composed of 20 isolates of Type 1, 16 of Type 2, 12 of Type 4 and 1 of a new mtDNA ...

Rapid and Simple Detection of Trichosporon asahii by Optimized Colony PCR

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Trichosporon asahii is the major pathogen causing invasive trichosporonosis. Conventional methods of its detection are time‐consuming or costly and often require complex DNA extraction and purification steps, which hinders rapid clinical diagnosis. In this study, we evaluated colony PCR, which directly uses colonies or trace clinical samples as the ...

Advanced Fungal Control With Metallic Nanoparticles: A Comprehensive Review of Nanoparticle Tracking Analysis (NTA) for Particle Concentration Characterization

ChemistrySelect, Volume 11, Issue 12, 26 March 2026.
Metallic nanoparticles are emerging as potent antifungal agents, yet their efficacy is rarely quantified on a particle basis. Here, we demonstrate how nanoparticle tracking analysis (NTA), together with a newly proposed Particle Efficiency Index (PEI), can relate nanoparticle concentration to fungal inoculum load, enabling more rigorous and comparable ...

Paracoccidioides Spp.: Virulence Factors and Immune‐Evasion Strategies

Mediators of Inflammation, Volume 2017, Issue 1, 2017., 2017
Paracoccidioides spp. are dimorphic fungal pathogens responsible for one of the most relevant systemic mycoses in Latin America, paracoccidioidomycosis (PCM). Their exact ecological niche remains unknown; however, they have been isolated from soil samples and armadillos (Dasypus novemcinctus), which have been proposed as animal reservoir for these ...

An unusual case of mediastinal mass due toFonsecaea pedrosoi [PDF]

European Respiratory Journal, 2006
Phaeohyphomycosis is a disease caused by dematiaceous fungi. Here, the first culture-proven case of mediastinal mass due toFonsecaea pedrosoiis reported.The patient was a 40-yr-old male who had presented with history of dyspnoea and dysphagia.Computed tomography of the chest disclosed a mediastinal mass.

A case of chromoblastomycosis caused by Fonsecaea pedrosoi: challenge in diagnosis

Bali Medical Journal, 2023
Link of Video Abstract: https://youtu.be/9CxOCuDn4f4   Background: Chromoblastomycosis (CBM) is a chronic, granulomatous mycosis of the skin and subcutaneous tissue produced by the traumatic inoculation of various dematiaceous fungi. CBM lesions are clinically polymorphic and often misdiagnosed as multiple infectious and noninfectious diseases.

Antimicrobial Properties of Plant Essential Oils against Human Pathogens and Their Mode of Action: An Updated Review

Evidence-Based Complementary and Alternative Medicine, Volume 2016, Issue 1, 2016., 2016
A wide range of medicinal and aromatic plants (MAPs) have been explored for their essential oils in the past few decades. Essential oils are complex volatile compounds, synthesized naturally in different plant parts during the process of secondary metabolism.
