Abstract:
Trichoderma is a saprophytic fungus that is used worldwide as a biocontrol and biofertilizer agent. Although considered nonpathogenic until recently, reports of human infections produced by members of the Trichoderma genus are increasing. Numerous sources of infection were proposed based upon patient data and phylogenetic analysis, including air, agriculture, and healthcare facilities, but the deficit of knowledge concerning Trichoderma infections makes patient treatment difficult. These issues are compounded by isolates that present profiles which exhibit high minimum inhibitory concentration values to available antifungal drugs. The aim of this review is to present the global distribution and sources of infections that affect both immunocompetent and immunocompromised hosts, clinical features, therapeutic strategies that are used to treat patients, as well as highlighting treatments with the best responses. In addition, the antifungal susceptibility profiles of Trichoderma isolates that have emerged in recent decades were examined and which antifungal drugs need to be further evaluated as potential candidates to treat Trichoderma infections are also indicated.
Insights
Human infections from Trichoderma, a common biofertilizer, are rising. This review details global infections, clinical features, and effective antifungal treatments for Trichoderma, aiding patient care.
Area of Science:
- Mycology
- Infectious Diseases
- Antimicrobial Resistance
Background:
- Trichoderma, a widely used biofertilizer and biocontrol agent, is increasingly implicated in human infections.
- Growing reports highlight the challenge of treating Trichoderma infections due to high antifungal drug resistance.
Approach:
- This review synthesizes global data on Trichoderma infection sources and distribution.
- It examines clinical manifestations, therapeutic strategies, and treatment outcomes.
- Antifungal susceptibility profiles of recent Trichoderma isolates are analyzed.
Key Points:
- Infections affect both immunocompetent and immunocompromised individuals.
- Sources of infection include air, agriculture, and healthcare settings.
- Treatment is complicated by isolates with high minimum inhibitory concentrations to standard antifungals.
Conclusions:
- Effective therapeutic strategies and optimal antifungal treatments are highlighted.
- Further evaluation of specific antifungal drugs is recommended for emerging Trichoderma infections.
