Antibacterial test of the X33 antifungal extract against P. digitatum . Green asexual spores (conidia) form at the centre of the colony, surrounded by a broad band of white mycelium. Colonization of nonsterile anatomical sites in humans is common. Additionally, control of the disease is further complicated by the emergence of drug-resistant strains due to the extensive use of triazole antifungal drugs.
