Would global warming bring an increase of invertebrate-associated cutaneous invasive fungal infections?

mycolabadmin

This paper discusses how invertebrate bites (from insects, spiders, and other small creatures) can transmit dangerous fungal infections to humans by directly injecting fungi into the skin. These infections are rare but serious, often causing tissue death and requiring amputation. As global warming increases temperatures, insect populations will expand into new areas, become more aggressive, and fungi may adapt to survive at higher temperatures, potentially making these infections more common and dangerous in the future.

Effect of Rare, Locally Isolated Entomopathogenic Fungi on the Survival of Bactrocera oleae Pupae in Laboratory Soil Conditions

mycolabadmin

Researchers tested seventeen types of fungi found in Greek olive groves to see if they could kill olive fruit flies, which damage about 30% of olive crops. They applied the fungi to fly pupae in soil and without soil, then tracked how many flies died and how much fungal growth appeared. Several fungi types, especially Aspergillus flavus and A. keveii, were very effective at killing the flies and could potentially replace harmful chemical pesticides used in olive farming.

Hidden treasures of herbaria – even small collections contain a wealth of diversity: the powdery mildews of the North Carolina State Larry F. Grand Mycological Herbarium

mycolabadmin

Scientists examined preserved powdery mildew samples stored in a university herbarium and discovered four previously unknown fungal species using DNA analysis. The study shows that even small museum collections contain valuable hidden biodiversity that cannot be discovered through visual examination alone. This research highlights why it is important to preserve and maintain herbarium collections rather than discard them due to space or funding constraints, as they serve as crucial resources for understanding fungal diversity and disease.

Introducing a global database of entomopathogenic fungi and their host associations

mycolabadmin

Scientists have created a global database called EntomoFun 1.0 that brings together information about fungi that naturally infect insects and other arthropods. The database contains nearly 1,800 records of different fungal species and the insects they infect, collected from scientific literature and museum specimens. This resource helps researchers understand where these fungi are found, which insects they target, and how they might be used for pest control or studied for their ecological importance.

Cryptococcus: Emerging host risk factors for infection

mycolabadmin

This scientific review examines why some people without HIV are getting serious Cryptococcus infections and becoming very sick. Researchers found that people with liver problems, kidney disease, diabetes, cancer, and autoimmune diseases face much higher risk. The review also identifies new drugs and therapies that can surprisingly increase infection risk, highlighting the importance of understanding individual patient factors when treating these dangerous fungal infections.

Select and Resequence Methods Enable a Genome-Wide Association Study of the Dimorphic Human Fungal Pathogen Coccidioides posadasii

mycolabadmin

Scientists developed a new method to understand how different strains of the fungus Coccidioides posadasii, which causes Valley Fever, respond to temperature changes. By mixing multiple fungal strains together and sequencing their DNA after growing them at different temperatures, they identified a gene that helps determine whether the fungus grows better in hot (body temperature) or cool (environmental) conditions. This discovery could help explain how this dangerous fungus adapts to human infection and may lead to better treatments for Valley Fever.

Editorial: Fungal virulence

mycolabadmin

Fungal infections are becoming more dangerous and common worldwide, especially as climate change warms the planet. Scientists are studying how fungi develop the ability to cause disease, focusing on features like their stickiness to human tissues and ability to form protective biofilms. Recent research shows that specific proteins and growth conditions affect how dangerous different fungi are and how our immune system responds to them. Understanding these mechanisms could help doctors develop better treatments and vaccines against fungal infections.

Plant Pathogenic Fungi Special Issue: Genetics and Genomics

mycolabadmin

This scientific review discusses how modern genetics and genomics tools are helping researchers better understand and manage plant diseases caused by fungi. Seven research studies are presented covering topics like identifying different fungal species, understanding how fungi attack plants, and finding natural alternatives to chemical fungicides. The research emphasizes the importance of monitoring fungal diseases and developing crops that resist infection to protect global food production.

Regulation and functions of alternative polyadenylation in fungi

mycolabadmin

This review explains how fungi use a process called alternative polyadenylation to create different versions of proteins from the same gene. Think of it like different recipes using the same ingredients but with different instructions. This process is important for fungal survival, growth, and ability to cause disease. Scientists are developing new tools and techniques to study this process, which could lead to better treatments for fungal infections.

Effect of Rare, Locally Isolated Entomopathogenic Fungi on the Survival of Bactrocera oleae Pupae in Laboratory Soil Conditions

mycolabadmin

Researchers tested seventeen types of fungi as natural pest control for the olive fruit fly, a major pest that damages olive crops in Greece. They found that several fungal species, especially Aspergillus flavus and Aspergillus contaminans, were highly effective at killing fly pupae in soil conditions. These fungi could offer farmers an eco-friendly alternative to toxic chemical pesticides, helping improve olive oil quality while protecting beneficial insects.
