Aspergillus fumigatus: A Dual Threat in Resistance
Samantha N. Peltak, Tomoko Y. SteenAspergillus fumigatus is an opportunistic fungal pathogen of increasing concern in both medical and agricultural fields. In clinical settings, it is the primary cause of aspergillosis, which can cause a spectrum of symptoms ranging from allergic reactions to life-threatening invasive infections, particularly in immunocompromised individuals. The global burden of invasive aspergillosis is rising, exacerbated by the emergence of antifungal resistant strains, especially to triazoles, which are frontline therapeutics and widely used as an antifungal agent in farming. These resistant spores can infect vulnerable human hosts, undermining treatment potential and increasing mortality rates. The dual impact of A fumigatus as a crop contaminant and a human pathogen highlights the urgent need for integrated public health strategies and the importance of the One Health program. Antifungal stewardship and research into novel diagnostics and therapeutics are critical to address this emerging threat at the intersection of healthcare, agriculture, and the environment. This review addresses the burden of A fumigatus in agriculture and healthcare by exploring a One Health perspective, describing the effects on agriculture, outlining clinical presentations, and analyzing several virulence factors and their potential value for creating a novel treatment option.
