Morpho-phylogenetic evidence reveals novel hyphomycetous fungi on medicinal plants in Southwestern China

mycolabadmin

Scientists discovered twelve new species of fungi growing on medicinal plants in southwestern China. Using microscopy and DNA analysis, researchers identified these fungi and studied how they relate to each other genetically. The study is important because these fungi can affect the quality of herbal medicines that millions of people use worldwide. This research helps protect medicinal plant quality and expands our knowledge of fungi in nature.

Aspergillus terreus sectorization: a morphological phenomenon shedding light on amphotericin B resistance mechanism

mycolabadmin

This study investigated why some strains of the fungus Aspergillus terreus are resistant to amphotericin B, an important antifungal medicine. Researchers compared a resistant strain with a mutated version that became susceptible to the drug. They found that certain genes called P-type ATPases are more active in resistant strains and may help the fungus pump ions and alter its cell membrane to survive the drug. Additionally, mutations in genes responsible for producing secondary metabolites were linked to the visible changes seen when fungal cultures degenerate.

Climate Change, Natural Disasters, and Cutaneous Fungal Infections

mycolabadmin

Climate change and natural disasters are creating conditions that allow fungal infections to spread more easily and affect people in new ways. Warmer temperatures help fungi adapt to infect humans, while floods, earthquakes, and hurricanes expose people to fungal spores and create wounds through which infections can enter. Doctors need to be alert for unusual fungal infections after disasters, especially since some of these infections can cause serious complications and resist common treatments.

Antifungal susceptibility testing of Microsporum canis isolated from the skin of dermatologically healthy cats

mycolabadmin

Researchers found that about 5% of healthy cats in Chile carry a fungal infection called Microsporum canis that can spread to humans. The concerning discovery is that all strains tested were resistant to fluconazole, a commonly used antifungal medication. The study shows that indoor cats are at higher risk of carrying this fungus and suggests that screening healthy cats could help prevent transmission to people who have close contact with them.

ABPA in post-tuberculosis lung disease: A diagnostic pitfall or genuine entity?

mycolabadmin

This article addresses confusion between two Aspergillus lung infections that commonly occur after tuberculosis: ABPA and CPA. While they have overlapping symptoms and test results, they require different treatments—ABPA responds to short-term steroids while CPA needs prolonged antifungal drugs. Importantly, giving steroids for misdiagnosed CPA can be harmful, so doctors should be cautious about diagnosing ABPA in tuberculosis survivors and consider CPA instead.

Primary cutaneous mixed infection with Cryptococcus uniguttulatus and Mycobacterium tuberculosis

mycolabadmin

A 43-year-old man had persistent facial skin lesions for seven years that initially appeared to be fungal infection caused by Cryptococcus uniguttulatus. Standard antifungal treatments failed to completely cure the condition. Advanced genetic testing revealed the lesions were actually caused by two simultaneous infections: the fungus and tuberculosis bacteria. Once both infections were properly identified and treated with appropriate medications, the skin lesions finally healed.

Diaporthe foeniculina and D. eres, in addition to D. ampelina, may cause Phomopsis cane and leaf spot disease in grapevine

mycolabadmin

Researchers found that three different fungal species, not just one, cause a disease called Phomopsis cane and leaf spot in grapevines grown in Southern Europe. While Diaporthe ampelina remains the primary culprit, two other species (D. eres and D. foeniculina) can also cause the same disease symptoms. Interestingly, these different fungi prefer different temperatures for growth, which means farmers may need to adjust their disease management strategies based on which species is present in their vineyards.

Histological Dissection of Fusarium-Banana Interaction Using a GFP-Tagged Subtropical Race 4 Strain of Fusarium oxysporum f. sp. cubense on Banana Cultivars with Differing Levels of Resistance

mycolabadmin

Researchers used fluorescently-labeled fungal strains to visualize how banana wilt disease spreads inside banana plants. They found that resistant banana varieties can slow down the fungus by forming blockages (called tyloses) in their water-conducting vessels, though the fungus can still initially enter the plant. The study showed that the rhizome, an underground stem-like structure, is the key location where resistant plants successfully contain the fungus, which helps explain why some banana varieties are naturally more resistant to this devastating disease.

Epidemiology of Onychomycosis in the United States Characterized Using Molecular Methods, 2015–2024

mycolabadmin

This large study examined over 710,000 nail samples to identify which fungi cause nail infections in the United States. Using modern molecular testing combined with microscopic analysis, researchers found that while the fungus T. rubrum is most common, other molds and yeasts cause many infections too. Importantly, women and older adults are more likely to have infections from these other organisms, which are often harder to treat with standard antifungal medications.

Tackling Conifer Needle Cast and Ash Dieback with Host-Derived Microbial Antagonists Exhibiting Plant Growth-Promoting Traits

mycolabadmin

Scientists discovered native bacteria from European ash and Scots pine trees that can fight two destructive forest diseases: ash dieback and needle cast. These bacteria not only inhibit the disease-causing fungi but also help trees grow better by improving nutrient uptake. This natural approach offers an eco-friendly alternative to fungicide sprays for protecting forests.
