A case report of childhood onychomycosis caused by the rare yeast Kodamaea ohmeri

mycolabadmin

A 5-year-old girl in Vietnam developed a nail infection caused by a rare yeast called Kodamaea ohmeri, which typically affects adults with diabetes or weak immune systems. The infection, appearing as white discoloration on the nails, was successfully treated with a topical antifungal cream applied three times daily for one month. This is the first reported case of this rare yeast causing nail infection in a child in Vietnam, and it demonstrates that topical treatment can be effective for fungal nail infections in children whose nails are thinner than adults.

Biological characterization and in vitro fungicide screening of a new causal agent of walnut leaf spot in Guizhou Province, China

mycolabadmin

Researchers in China discovered that a fungus called Didymella segeticola is causing a serious leaf spot disease in walnut trees in Guizhou Province. They studied how this fungus grows under different conditions and tested 20 different fungicides to find the most effective treatments. Two fungicides—difenoconazole and tetramycin—were found to be particularly effective at stopping the fungus, offering practical solutions for protecting walnut crops.

Eight Fungal Species Associated with Ambrosia Beetles in Korea

mycolabadmin

This research identifies eight types of fungi that live in partnership with ambrosia beetles in Korea. These fungi are food sources for beetle larvae and adults. The study found that some fungi have specific relationships with particular beetle species, while others can associate with multiple beetle types. This work helps scientists understand how beetles spread fungi and potentially cause tree diseases like oak wilt.

Morphological and Phylogenetic Characterization of Trichomerium koreanum sp. nov. and Exophiala radicis Belonging to Chaetothyriales Fungi in Korea

mycolabadmin

Scientists discovered a new type of black yeast fungus in Korea called Trichomerium koreanum, found on a longhorn beetle. They also identified another fungus called Exophiala radicis in Korean soil for the first time. These fungi are related to species that can sometimes cause infections in humans and animals. The researchers used genetic testing and microscopy to confirm these findings and understand how these fungi are related to other similar species.

Morphological and phylogenetic analyses reveal two new species of Tubeufia (Tubeufiales, Tubeufiaceae) from freshwater habitats in China

mycolabadmin

Scientists discovered two new species of fungi called Tubeufia living in freshwater streams in China’s Hainan Province. By examining the fungi under microscopes and analyzing their genetic material, researchers confirmed these were entirely new species distinct from all previously known Tubeufia. These findings add to our understanding of fungal diversity in freshwater ecosystems and demonstrate how different scientific approaches together provide the clearest picture of fungal species.

Diversity of Culturable Fungi in Two-Phase Olive Mill Waste, a Preliminary Evaluation of Their Enzymatic Potential, and Two New Trichoderma Species

mycolabadmin

Scientists discovered 31 different fungal species living in olive mill waste, including two previously unknown species. These fungi have the ability to break down tough plant materials and remove harmful dyes from waste, making them useful for cleaning up environmental pollution. This research suggests these fungi could be used to transform olive oil production waste into useful products, supporting a circular economy.

Targeted long-read sequencing analysis and antifungal susceptibility profiles of Sporothrix schenckii isolates from Thailand

mycolabadmin

This research examined a fungal infection called sporotrichosis found in Thailand, particularly in cats and humans. Scientists used advanced DNA sequencing technology to accurately identify which species of the fungus caused the infections and understand how they are related to each other. They also tested how well common antifungal medications work against these fungi, finding that some strains have become resistant to itraconazole, the main drug used to treat sporotrichosis.

Rhizosphere Bacterial Communities Alter in Process to Mycorrhizal Developments of a Mixotrophic Pyrola japonica

mycolabadmin

This study examines how bacterial communities in soil around plant roots change as fungi develop their associations with a mixotrophic plant called Pyrola japonica. The researchers found that bacterial diversity decreases when fungal colonization is at its peak, and these bacterial communities remain relatively stable even after the fungi begin to degenerate. The bacteria, particularly species from the Rhizobiales and Actinomycetales groups, appear to help support the fungal-plant partnership.

Ascoidea xinghuacunensis sp. nov., a novel ascomycetous yeast species from Xinghuacun Fenjiu old workshop, Shanxi province of China

mycolabadmin

Scientists discovered a new type of heat-loving yeast in a traditional Chinese liquor-making workshop in Shanxi province. This yeast, named Ascoidea xinghuacunensis, is the first member of its rare genus to be found in China and can survive at higher temperatures than its relatives. The discovery was made by analyzing the genetic material and physical characteristics of yeast samples collected from fermentation facilities, expanding our knowledge of microscopic life in food production environments.

Morphological and Phylogenetic Characterization of Endophytic Fungi Isolated from Brown Algae (Phaeophyceae) in Korea

mycolabadmin

Researchers in Korea discovered three previously unknown fungal species living inside brown seaweed called Sargassum. These fungi were identified using genetic analysis and microscopy. The discovery suggests that seaweed hosts diverse fungal communities that could have useful properties, such as producing compounds with antimicrobial and anti-cancer potential. This research expands our understanding of marine fungal diversity and its possible applications in medicine and biotechnology.
