Abstract:
Antifungal resistance (AFR), an emerging and significant threat to humanity, receives far less attention than antibacterial resistance. AFR management is plagued by rising incidence in both immunocompromised and immunocompetent populations, zoonotic infections, limited fungal diagnostics, limited antifungal armamentarium with even fewer in pipeline, cross-resistance between environmental fungicides and clinically used antifungals, lack of strong antifungal stewardship programs, limited applications of novel strategies for human AFR, to name a few. In this review, we compile available information, current advances and our perspectives on major challenges in the origin and management of AFR. We conduct systematic review of all available publications on standard databases using search terms related to AFR from the past until January 2026. We consider all major publications on key questions in AFR. We focus on the following aspects of AFR: environmental drivers, AFR and "One Health" perspective, climate change and AFR, emerging fungal zoonoses, fungal diagnostic challenges and advances, key resistant fungal pathogens, antifungal stewardship programs, summarize the use of newer antifungals and their clinical trials, and provide an overview of novel strategies for tackling AFR, like the potential use of mycoviruses and vaccines. We also briefly present our perspective on the future of AFR progression and management.
Insights
Antifungal resistance (AFR) is a growing global threat, exacerbated by limited diagnostics and treatments. This review addresses key challenges and novel strategies for managing AFR in humans and animals.
Area of Science:
- Mycology
- Infectious Diseases
- Public Health
Background:
- Antifungal resistance (AFR) is an escalating global health concern, yet it receives less attention than antibacterial resistance.
- AFR incidence is rising in both immunocompromised and immunocompetent individuals, complicated by factors like zoonotic potential and limited diagnostics.
Purpose of the Study:
- To compile current information, advances, and perspectives on the major challenges in the origin and management of antifungal resistance.
- To systematically review existing literature on antifungal resistance, focusing on environmental drivers, the "One Health" perspective, and climate change impacts.
Main Methods:
- Conducted a systematic review of publications on standard databases using search terms related to antifungal resistance up to January 2026.
- Focused on key aspects including environmental drivers, "One Health," climate change, fungal zoonoses, diagnostics, resistant pathogens, stewardship, and novel strategies.
Main Results:
- Identified significant challenges in AFR management, including limited diagnostics, a narrow antifungal pipeline, and cross-resistance issues.
- Highlighted the need for robust antifungal stewardship programs and explored emerging fungal zoonoses and their links to environmental factors.
Conclusions:
- AFR presents a complex, multifaceted threat requiring a "One Health" approach, integrating human, animal, and environmental health strategies.
- Novel strategies, including mycoviruses and vaccines, show promise for combating AFR, alongside improved diagnostics and stewardship.
