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.

Low Temperature Enhances N-Metabolism in Paxillus involutus Mycelia In Vitro: Evidence From an Untargeted Metabolomic Study

mycolabadmin

Researchers studied how a common forest fungus (Paxillus involutus) responds to cold temperatures like those found in spring and autumn. Surprisingly, even though the fungus grew slower in the cold, it actually increased its nitrogen uptake and production of amino acids, the building blocks of proteins. This suggests the fungus has special adaptation mechanisms to thrive in cold environments, which could be important for understanding how climate change might affect forest health.

Pathogenic potential of polyextremotolerant fungi in a warming world

mycolabadmin

Certain fungi can survive extremely harsh conditions like extreme temperatures and dry environments, and many of these same species can cause infections in humans. As the planet warms due to climate change, these fungi are becoming better adapted to higher temperatures, which makes them more dangerous as human pathogens. Scientists are working to better understand these fungi and develop new treatments and vaccines to protect people from fungal infections.

Discovery of the first resinicolous fungus in Mycosphaerellales (Dothideomycetes): Resinomelania communis from conifer resins in Poland

mycolabadmin

Scientists discovered a new fungus species living on tree resins from conifer trees in Poland. This fungus, named Resinomelania communis, represents the first known fungus in its evolutionary group that specializes in living on sticky tree resins. The discovery was made by identifying 13 fungal strains from four different conifer species using DNA analysis and studying their physical characteristics.

Differential hypo-osmotic stress responses and regulatory mechanisms of Aspergillus sydowii in amphipod guts and hadal sediments

mycolabadmin

Scientists isolated a fungus from the gut of deep-sea amphipods in the Mariana Trench and discovered how it uniquely adapts to low-salt conditions. Unlike other fungal strains from different habitats, this gut fungus showed special abilities to survive and even thrive when salt levels dropped dramatically. The researchers found that the fungus rapidly rewired its genes and cellular structures to maintain water balance and protect itself, revealing how life in extreme deep-sea environments drives evolution of novel survival strategies.
