The secreted polyketide boydone A is responsible for the anti‐Staphylococcus aureus activity of Scedosporium boydii
TLDR
Results suggest that this six‐membered cyclic polyketide could be one of the virulence factors of the fungus, and genes involved in the synthesis of this secreted metabolite are currently being identified in order to confirm the role of thispolyketide in pathogenesis.

TLDR
A novel antifungal antibiotic, YM-193221, was found in the culture broth of a fungus, Pseudallescheria ellipsoidea, and exhibited potent antIFungal activity against Candida albicans and also inhibited mannan synthesis in the yeast cell wall.
