This research examines how the fungus that causes white nose syndrome in bats responds to different levels of copper. The fungus uses special proteins to grab copper when it’s scarce and protect itself when copper is abundant. Understanding these survival strategies helps explain how the fungus thrives in bat caves and different soil environments.
Scientists have identified and formally named 8 new species of Bisifusarium, a genus of fungi found in cheese, soil, and some human infections. Using genetic analysis and careful observation of fungal structures, researchers studied 116 fungal samples collected from around the world. This work more than doubled the known number of Bisifusarium species from 16 to over 24, providing clearer identification methods for future research in food science and medicine.
Doctors in Thailand have identified a new drug-resistant fungal infection caused by Trichophyton indotineae, a fungus that doesn’t respond to common antifungal medication terbinafine. Five patients were diagnosed with this resistant skin infection that caused rashes on various body parts and failed to improve with standard treatments. The research shows that a simple urease test can help doctors quickly identify this resistant fungus, and a different drug called itraconazole appears to work better for treatment. This is the first time this resistant fungus has been confirmed in Thailand, suggesting it is spreading globally.
This study compared three laboratory machines that identify fungi using a technique called MALDI-TOF mass spectrometry. Researchers tested 77 different fungal samples on each machine to see which one worked best. All three machines were useful for routine lab work, but they each worked best at different time points after the fungi started growing. The study shows that labs should be aware of when to test their samples for the most accurate results.
Rice blast disease caused by the fungus Magnaporthe oryzae threatens global rice production. This study identified and studied five proteins (GET components) that help the fungus insert special proteins into cell membranes, a process essential for the fungus to infect rice plants. Researchers found that two of these proteins are critical for the fungus to grow, reproduce, and cause disease, while a third one actually reduces the fungus’s ability to infect plants. This discovery could lead to new strategies to control rice blast disease.
Scientists discovered two previously unknown types of fungi – one living in the roots of seagrass in Mauritius and another found in salty soils in the Czech Republic. These fungi belong to a special group that thrives in salty environments. By studying their DNA and physical characteristics, researchers confirmed these are entirely new species and determined where they fit in the fungal family tree. The findings suggest that these salt-loving fungi are more widespread than previously thought and can live in both ocean and inland salty habitats.
Researchers in Costa Rica discovered that a dangerous fungal disease affecting sea turtle eggs is more widespread than previously known. The disease, called sea turtle egg fusariosis, is caused by two types of fungi that can kill developing turtle embryos. Scientists used advanced genetic testing to identify these fungi at major turtle nesting beaches on both coasts of Costa Rica, finding one fungus present at all locations while another was found only on the Caribbean coast. While the disease is not severely harming Costa Rican sea turtles yet, environmental changes could make it worse in the future.
Scientists have discovered that two types of fungi called Arachnopeziza species are the closest living relatives to powdery mildew fungi, which cause plant diseases. Unlike powdery mildews, these Arachnopeziza fungi can be easily grown in the lab and genetically modified. By studying these more manageable fungi, researchers can better understand how powdery mildew fungi became obligate parasites that must live on plants, potentially leading to better ways to control this widespread plant disease.
Scientists have created a comprehensive online database called EntomoFun 1.0 that catalogs nearly 1,800 documented cases of fungi that infect insects worldwide. This database brings together information scattered across hundreds of scientific papers and museum collections, showing which fungal species infect which insects and where these interactions occur geographically. This tool will help researchers understand how these fungal pathogens affect insect populations and ecosystems, and may eventually lead to better pest management strategies.
A five-year-old girl developed large swollen lumps on her buttock and thigh that were initially thought to be tuberculosis or cancer. Doctors took a tissue sample and found it was caused by a rare fungus called Basidiobolus meristosporus. Using advanced DNA sequencing techniques, they identified the exact fungus species and treated her successfully with an antifungal medication called itraconazole, leading to complete healing within six weeks.
