First case report of tinea corporis caused by Trichophyton indotineae in Latin America

mycolabadmin

A 21-year-old woman in Argentina developed a persistent skin infection caused by a fungus called Trichophyton indotineae, likely acquired during travel to Mexico. The infection did not respond to common antifungal medications like terbinafine, but responded well to treatment with a special formulation of itraconazole that was completely effective within four weeks. This case represents the first documented occurrence of this emerging fungal pathogen in Latin America and highlights the importance of molecular identification when standard treatments fail.

Simultaneous Detection of Four Madurella Species Using Loop-Mediated Isothermal Amplification (LAMP) for Eumycetoma Diagnosis

mycolabadmin

Scientists developed a simple new test to identify four types of fungi that cause a serious tropical disease called eumycetoma. Unlike previous tests that required expensive equipment and multiple reactions, this new test works in one tube using simple heating instead of complex thermal cycling. The test can detect the fungi in about 45 minutes and works reliably in remote areas with limited resources.

Simplicillium sinense sp. nov., a novel potential pathogen of tinea faciei

mycolabadmin

Researchers identified a new fungal species called Simplicillium sinense that caused a facial skin infection (tinea faciei) in a 46-year-old man with diabetes. The fungus was resistant to most common antifungal medications but responded well to terbinafine treatment. This is the first reported case of a Simplicillium infection causing facial ringworm, expanding our understanding of rare fungal pathogens.

Professor Emel Tümbay (1941–2025): A Pioneer of Medical Mycology in Türkiye

mycolabadmin

Professor Emel Tümbay was a pioneering scientist who transformed medical mycology in Türkiye from 1941 to 2025. She established the country’s first diagnostic mycology laboratory, wrote important reference books, and trained many specialists who spread her knowledge throughout the nation. Her work helped doctors better understand and treat fungal diseases, and she is remembered as a dedicated educator and passionate scientist.

The frequency distribution of Aspergillus section Nigri from clinical and environmental samples in Iran

mycolabadmin

Researchers studied black mold species (Aspergillus section Nigri) found in hospitals and the environment across Iran. They identified eight different species and found that certain types like A. welwitschiae were more common in ear infections while A. tubingensis was more prevalent in soil and air. These findings are important because some of these molds cause serious infections in humans and understanding where they live helps doctors predict and treat infections.

A case of Blastomyces helicus pneumonia in a dog from a non-endemic region: diagnostic challenges and successful treatment outcome

mycolabadmin

A dog developed severe pneumonia from an emerging fungal infection called Blastomyces helicus after traveling to Utah and Idaho. Initial blood tests incorrectly suggested a different fungus, but laboratory culture and genetic testing identified the true culprit. The dog was successfully treated with an antifungal medication called itraconazole and made a complete recovery with careful monitoring over 6 months.

Editorial: Fungal virulence

mycolabadmin

This editorial discusses how fungi are becoming more dangerous to human health due to climate change and rising temperatures. Researchers are studying the specific mechanisms that make fungi harmful, including how they stick to human cells and form protective biofilms. The review highlights several important discoveries about different pathogenic fungi and suggests better ways to diagnose and treat fungal infections through understanding how environmental factors influence fungal behavior.

Inconsistencies within the proposed framework for stabilizing fungal nomenclature risk further confusion

mycolabadmin

Scientists who study fungi have been working to update how fungal species are named to match modern genetic understanding. A recent proposal tried to create rules for how clinical laboratories should report fungal names, but experts are concerned that the new framework has inconsistencies and may actually cause more confusion rather than clarify things. The authors of this letter point out that some fungi get special naming considerations while others don’t, and worry that allowing multiple names for the same organism contradicts years of effort to use one standard name per species.

Tinea genitalis profunda caused by Microsporum canis: A case report and literature review

mycolabadmin

A 23-year-old woman developed a severe fungal infection in the genital area caused by a fungus normally found on dogs. Her initial antibiotic treatment failed because the infection was actually fungal, not bacterial. After diagnosis through fungal culture, she was successfully treated with antifungal medications, though the infection left some scarring and discoloration. This case highlights how genital fungal infections can be difficult to diagnose because they look similar to bacterial infections.

BTK drives neutrophil activation for sterilizing antifungal immunity

mycolabadmin

BTK is a protein that helps neutrophils (immune cells) fight fungal infections, particularly Aspergillus fumigatus. A cancer drug called ibrutinib blocks BTK, which weakens neutrophil antifungal responses and increases the risk of serious fungal infections. The study found that GM-CSF may help restore some immune function in patients taking BTK-blocking drugs, offering a potential strategy to prevent these dangerous infections.
