Fungal infections are becoming more deadly due to the spread of drug resistance and the cessation of treatment options. After 11 years of research, scientists from McMaster University have discovered a new weakness in deadly fungi. A molecule called butyrolactol A dramatically weakens dangerous fungi. This allows existing antifungals to work again. Instead of directly killing the fungus, the molecule sabotages its vital internal system. The pathogen thus remains exposed to the drugs. This breakthrough could revive an entire class of antifungal drugs that were once considered obsolete.[2]
