Advancing automated identification of airborne fungal spores: guidelines for cultivation and reference dataset creation

Researchers developed standardized procedures to grow fungal spores in laboratories and prepare them for testing with automated detection devices. They tested 17 different fungal species commonly found in the air and created reference datasets to train computer algorithms to identify these spores. Two different detection technologies were evaluated, showing promising accuracies (55-95%) for identifying various fungal spores. This work provides a blueprint for other scientists to create reliable training data for automated air quality monitoring systems that track allergens and disease-causing fungi.

Fungal Spore Seasons Advanced Across the US Over Two Decades of Climate Change

Scientists studied fungal spores in the air across the United States from 2003 to 2022 and found that spore seasons are starting earlier due to climate change, particularly from warmer temperatures. These airborne fungal spores can trigger allergies and asthma symptoms in sensitive people. The research shows the amount of spores in the air is decreasing, but they arrive sooner in the year, which has important implications for managing allergies and public health.

Emerging Allergens: How Proallergenic Activity Disrupts Epithelial Barriers [Response to Letter]

Many people with allergies or asthma don’t know what’s causing their symptoms. Researchers are investigating whether fungi that grow on plants might be responsible for some of these unknown allergies. They found that certain plant fungi can trigger allergic and inflammatory responses in animal models, suggesting they could be allergens in humans. The team plans to identify the specific fungal proteins causing these reactions to develop better allergy diagnostic tests.

Biochemical characteristics of extracts from proallergenic microfungi Erysiphe palczewskii and Erysiphe convolvuli

Researchers studied two types of fungi that cause powdery mildew on plants and can trigger allergies in people who breathe in their spores. They discovered that these fungi contain proteins that act as allergens, including special proteins that help fungi survive stress. The fungi also contain high levels of linoleic acid, a fatty acid that can increase inflammation in the body. This research helps scientists understand why these fungi can cause allergic reactions and could help develop better diagnostic tools for fungal allergies.
