Inhibitory and synergistic effects of volatile organic compounds from bat caves against Pseudogymnoascus destructans in vitro

mycolabadmin

Researchers discovered that two natural compounds found in bat cave environments—isovaleric acid and ethyl methyl carbonate—can effectively kill the fungus that causes white-nose syndrome in bats. When used together, these compounds work even better than alone, disrupting the fungus’s cell membranes, causing it to produce too many reactive molecules (free radicals), and triggering cell death. This discovery offers hope for developing new treatments to protect bat populations that have been devastated by this disease in North America.

Synergistic inhibition of Aspergillus flavus by organic acid salts: growth, oxidative stress, and aflatoxin gene modulation

mycolabadmin

A dangerous fungus called Aspergillus flavus contaminates animal feed and produces harmful toxins called aflatoxins that can make animals sick. Researchers tested a combination of three salt-based organic acids commonly used as natural food preservatives and found they work together to kill this fungus much better than using them individually. The combination damages the fungus’s cell structure, creates harmful reactive oxygen inside the cells, and shuts down the genes that produce the toxins, making it an excellent safe option for protecting animal feed.

Three cases of easy to be misdiagnosed tinea of vellus hair

mycolabadmin

This case report describes three patients (ages 2-24) who had skin infections caused by a fungus called Microsporum canis that initially was misdiagnosed as eczema or other simple skin conditions. The infections involved fine vellus hair and required prolonged combined treatment with both oral and topical antifungal medications to fully resolve. The key lesson is that proper fungal testing and extended treatment similar to scalp ringworm protocols are necessary for treating these easily-missed infections.

Dermatophytosis in a Chilean fox: first case of Nannizzia gypsea in Lycalopex griseus and the need for a one health approach

mycolabadmin

A young wild Chilean fox was found with a skin infection caused by a fungus called Nannizzia gypsea, which lives in soil and can infect animals and humans. This is the first time this fungus has been documented in foxes anywhere. Doctors treated the fox with an antifungal cream and it recovered completely. The case highlights how increasing urbanization and contact between domestic pets, wild animals, and humans can spread fungal diseases, emphasizing the need for a coordinated public health approach.

Early changes in microRNA expression in Arabidopsis plants infected with the fungal pathogen Fusarium graminearum

mycolabadmin

Researchers studied how Arabidopsis plants respond to infection by the fungus Fusarium graminearum by examining changes in small RNA molecules called microRNAs. They found that the plant activates specific microRNAs early in infection, even before visible disease symptoms appear. Two particularly important microRNAs, miR855 and miR826a, were identified as potential key regulators of the plant’s defense response. These findings could help scientists develop crop varieties with improved resistance to fungal diseases that cause significant agricultural losses worldwide.

Deubiquitinase Ubp5 is essential for pulmonary immune evasion and hematogenous dissemination of Cryptococcus neoformans

mycolabadmin

Researchers studied a protein called Ubp5 that helps the fungus Cryptococcus neoformans cause disease in humans. By removing this protein, the fungus became much less harmful and the immune system could fight it better. The fungus with the missing protein had problems with its outer coating, couldn’t hide as well from the immune system, and couldn’t spread to the brain. This suggests that blocking Ubp5 could be a new way to help the body defend against this dangerous fungal infection.

Continuous debridement combined with short-term posaconazole therapy for cutaneous mucormycosis caused by Rhizopus oryzae infection secondary to acute myeloid leukemia: a case report

mycolabadmin

An 80-year-old patient with acute myeloid leukemia developed a serious fungal skin infection caused by Rhizopus oryzae on his lower leg. Doctors treated the infection by repeatedly cleaning out the infected tissue and giving him an antifungal medication called posaconazole for just one week. Despite the short treatment duration due to cost concerns, the patient’s wound gradually healed over four months through continued surgical care, showing that sometimes focused surgical treatment can be as effective as long-term medication.

A Case Report of Candidiasis Cellulitis in Long-Term Corticosteroid Use

mycolabadmin

A 54-year-old man developed a serious skin infection on his hand caused by Candida, a normally harmless fungus, because he had been taking corticosteroid injections for 15 years for breathing problems. Despite antibiotic treatment, the swelling and pain continued. Doctors discovered it was a fungal infection through lab tests and treated it with antifungal medication (fluconazole) after draining the infection, which completely healed within two weeks.

The Involvement of Glycerophospholipids in Susceptibility of Maize to Gibberella Root Rot Revealed by Comparative Metabolomics and Mass Spectrometry Imaging Joint Analysis

mycolabadmin

Maize plants can suffer from a serious root disease called Gibberella root rot caused by a fungus. Researchers studied two types of maize—one resistant and one susceptible to this disease—and found that certain fatty compounds called lysophospholipids are more abundant in the susceptible plants. When these compounds build up, they damage plant cells and help the fungus spread. The resistant plants can break down these harmful compounds more effectively. This discovery could help plant breeders create maize varieties that resist this damaging disease.

Inhibitive effect of Urginea epigea methanolic extract and silver/zinc oxide nanoparticles on Aspergillus and aflatoxin production

mycolabadmin

Researchers tested whether a plant called Urginea epigea could stop the growth of a dangerous fungus (Aspergillus flavus) that produces aflatoxins, which can harm humans and animals. The plant extract completely stopped fungus growth at high concentrations and significantly reduced the production of toxins by turning off the genes responsible for toxin production. This suggests that plant-based treatments could offer a natural alternative to synthetic chemical fungicides for protecting food from contamination.
