Aspergillus fumigatus is a saprophytic filamentous fungus that participates in environmental carbon and nitrogen cycles through the degradation of complex organic substrates. In addition to its ecological role, A. fumigatus is the primary causative agent of a spectrum of diseases depending on the immune status of the individual, the most lethal of which is invasive aspergillosis (IA). Treatment strategies for IA are limited and far too frequently fail. Despite the high rates of treatment failure, antifungal resistance remains relatively low, albeit rising at a concerning rate. Insights into this discrepancy between the rate of treatment failure and the rate of …
