How hot is too hot for fungi🔥?
Fungal ascospores, the survival structures of many mold species, can endure heat levels that rival those tolerated by bacterial spores like Bacillus subtilis.

Fungal infections are an often-overlooked challenge in public health, but Aspergillus fumigatus is an example of how serious the issue can become.
Increasing resistance to azole antifungals, which are essential treatments for patients with weakened immune systems, poses an urgent threat.
