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.
A farmer developed nodular skin lesions two weeks after a wrist injury during farming activities, which turned out to be sporotrichosis, a fungal infection caused by Sporothrix globosa. Skin biopsy revealed characteristic structures called asteroid bodies that helped suggest the diagnosis. The infection was confirmed through fungal culture and DNA testing, and was successfully treated with potassium iodide over six months.
This research examines dangerous fungal infections in greenhouse-grown cannabis plants. Scientists found that Fusarium fungi, which also infect grains, can infect cannabis flowers and produce harmful toxins (mycotoxins) that could harm consumers. The study identified that nearby tall fescue plants may be spreading these fungi into greenhouses. Different cannabis varieties showed different levels of toxin accumulation despite similar fungal colonization, suggesting some varieties may be naturally more resistant.
Juniperus formosana is a beautiful ornamental plant used in landscaping. In October 2024, researchers discovered that a fungus called Fusarium avenaceum was causing a blight disease on these plants in Kaili City, China, making the needles turn yellow and wither. Through detailed examination of the fungus under a microscope and DNA testing, scientists confirmed this is the first time this particular fungus has been found causing this disease on Juniperus formosana in China.
This paper reviews how armillarioid fungi, particularly Armillaria species, cause root rot disease in forests and orchards across the Northern Hemisphere. These fungi spread through underground root-like structures called rhizomorphs and can kill trees and damage crops over large areas. The authors discuss how to identify these fungi using modern genetic methods and explore environmentally friendly biological control options using beneficial bacteria, fungi, and nematodes as alternatives to chemical treatments.
A fungal disease called ophidiomycosis is spreading among wild snakes around the world. This disease is caused by a fungus that interacts with the natural bacteria living on snake skin and with oils naturally produced by the skin. Certain helpful bacteria on snake skin can fight off the fungus by producing special compounds, but when the fungus takes over, it damages these protective bacteria, leading to worse infection. Understanding these interactions could help develop new ways to protect snakes from this emerging disease.
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.
A middle-aged woman in India was admitted with severe headaches and was found to have a rare fungal infection of the brain (meningitis) caused by Candida glabrata, a type of yeast. She had recently been diagnosed with AIDS and had very low immune cell counts. Although doctors tried multiple antifungal medications, the yeast showed resistance to these drugs and the patient’s condition worsened, ultimately leading to her death. This case highlights how dangerous fungal infections can be in people with severely weakened immune systems.
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.
Researchers studied how a virus that helps control chestnut blight disease changes when it spreads between fungal cells. They found that when the virus passes through spores, it becomes less diverse, but when it spreads between fungal cells, diversity is maintained better. The fungal host’s genetics strongly influences how many viral variants survive transmission, which has important implications for using this virus as a disease control strategy.
