Closing the diagnostic gap in medical mycology: The LODDY Test for identification of Lodderomyces elongisporus

mycolabadmin

Researchers developed a simple and affordable test called the LODDY Test to identify a dangerous yeast called Lodderomyces elongisporus that is often mistaken for a similar but less dangerous yeast. This test uses color changes on a special culture medium to distinguish between different yeast species in just 48 hours without expensive equipment. The test works perfectly in laboratories worldwide and could help doctors in developing countries diagnose and treat serious fungal infections more quickly and accurately.

Successful Treatment of Fungal Dermatitis in a Bottlenose Dolphin (Tursiops truncatus)

A bottlenose dolphin at a Japanese aquarium developed a serious fungal infection on its tail fin while suffering from severe digestive problems and weight loss. The infection was caused by two types of fungi that are normally hard to treat because they resist many antifungal medications. Veterinarians successfully treated the dolphin using a combination of two antifungal drugs (voriconazole and terbinafine), surgical removal of dead tissue, and daily wound cleaning with special solutions. The dolphin’s wound eventually healed completely, and this is the first documented successful treatment of these particular fungal infections in bottlenose dolphins.

Aspergillus fumigatus ctf1 – a novel zinc finger transcription factor involved in azole resistance

mycolabadmin

Researchers discovered that a gene called ctf1 in a harmful fungus called Aspergillus fumigatus helps control how resistant the fungus is to antifungal medications like voriconazole. When this gene is removed, the fungus becomes more resistant to these drugs because it pumps them out more efficiently. Understanding this mechanism could help doctors develop better treatments for serious fungal infections in vulnerable patients.

Synergistic potential and apoptosis induction of Bunium persicum essential oil and its pure components, cuminaldehyde and γ-terpinene, in combination with fluconazole on Candida albicans isolates: in vitro and in silico evaluation

mycolabadmin

Researchers tested how Bunium persicum essential oil and its components work alongside the antifungal drug fluconazole against Candida albicans infections. Cuminaldehyde, a major component of the oil, showed the strongest effects when combined with fluconazole, making infection-causing cells die faster than each substance alone. This combination approach could help overcome drug-resistant fungal infections and offers a promising natural alternative to synthetic drugs alone.

The ATO gene family governs Candida albicans colonization in the dysbiotic gastrointestinal tract

mycolabadmin

This study shows that the fungus Candida albicans uses a family of protein transporters called ATO to absorb acetate, a fatty acid produced by gut bacteria. When mice were treated with antibiotics that killed their beneficial bacteria, C. albicans could colonize their guts better if it had working ATO transporters. The research reveals that fungi have evolved special systems to take advantage of nutrients left behind when the normal gut bacteria are disrupted, which helps explain why fungal infections are more common after antibiotic use.

Yeast Diversity on Sandy Lake Beaches Used for Recreation in Olsztyn, Poland

mycolabadmin

Researchers studied yeasts living in sand from four recreational lakes in Poland over two summers. They found 62 different yeast species, including 8 potentially harmful types that can cause infections in humans. The study shows beach sand contains significant microbial contamination that should be regularly monitored to protect swimmers, especially people with weakened immune systems or skin injuries.

Transposons and accessory genes drive adaptation in a clonally evolving fungal pathogen

mycolabadmin

Researchers studied how a fungal plant pathogen called Fusarium oxysporum rapidly adapts to new environments by analyzing genetic changes during repeated passages through tomato plants and laboratory media. They discovered that jumping genes (transposons) were responsible for most mutations driving adaptation, and surprisingly found that genes located in specialized ‘accessory’ regions of the fungus’s genome controlled important functions like growth and virulence. This research reveals how fungal pathogens can evolve quickly to become better competitors or invaders.

Co-Infection of Pulmonary Aspergillosis and Cryptococcal Meningitis in an HIV-Positive Patient: A Case Report

mycolabadmin

This case describes a 46-year-old man with advanced HIV who developed two serious fungal infections simultaneously: a lung infection caused by Aspergillus fungus and meningitis caused by Cryptococcus fungus. Despite receiving appropriate antifungal medications, his condition worsened and he unfortunately died. The case highlights how people with very low immune cell counts are at high risk for multiple life-threatening fungal infections and emphasizes the importance of early HIV testing and screening for fungal infections.

Contamination of fungal genomes of Onygenaceae (Phylum Ascomycota) in public databases: incidence, detection, and impact

mycolabadmin

Scientists found that many fungal genome sequences stored in public databases contain unwanted bacterial DNA that can interfere with research results. They developed a method to identify and remove this contamination using related high-quality fungal genomes as reference. After cleaning four contaminated genomes, the quality improved significantly and the contamination dropped from 5-12% to below 3%, demonstrating that careful screening is essential for reliable genetic research.

Evaluation of Antifungal Activity Against Candida albicans Isolates From HIV-Positive Patients with Oral Candidiasis in a Major Referral Hospital, West Java, Indonesia

mycolabadmin

This study examined fungal infections in HIV-positive patients’ mouths at an Indonesian hospital. Researchers identified which Candida species caused the infections and tested how well common antifungal medications worked against them. They found that while a specific antifungal drug (fluconazole) was effective in most cases, some infections showed resistance, suggesting the need for careful monitoring and personalized treatment approaches.
