This research studies how a fungus called Nannizzia gypsea forms protective biofilms on skin and hair, making infections harder to treat. Scientists grew the fungus in the lab and on real human hair, discovering it creates thick slime-like protective layers containing proteins, sugars, and DNA. The fungus also produces enzymes that break down keratin (the main protein in skin and hair) and activates drug-pumping proteins that help it resist antifungal medications. Understanding these defense mechanisms could help develop better treatments for fungal skin infections that are currently difficult to cure.
