An Immunocompromised Mouse Model of Candida auris Systemic Infection

Area of Science:

• Mycology
• Infectious Diseases
• Pharmacology

Background:

• The emergence of multidrug-resistant Candida auris necessitates novel antifungal agents.
• Systemic candidiasis, particularly from C. auris, poses a significant global health threat.
• Existing in vivo models for testing antifungal efficacy require refinement to mimic predisposing conditions.

Purpose of the Study:

• To develop and describe an immunocompromised mouse model for hematogenously disseminated Candida auris infection.
• To establish a relevant in vivo system for evaluating novel antifungal compounds against C. auris.
• To provide a platform for preclinical testing of therapeutic strategies for invasive candidiasis.

Main Methods:

• Establishment of an immunocompromised mouse model.
• Induction of hematogenously disseminated infection with Candida auris.
• Characterization of infection parameters relevant to systemic candidiasis.

Main Results:

• Successfully created a reproducible immunocompromised mouse model of disseminated C. auris infection.
• The model mimics key aspects of human systemic candidiasis, including dissemination.
• Demonstrated the model's potential utility for evaluating antifungal compound efficacy.

Conclusions:

• The described immunocompromised mouse model is a valuable tool for studying C. auris pathogenesis.
• This model can facilitate the preclinical evaluation of new antifungal drugs targeting multidrug-resistant Candida auris.
• Further research using this model may accelerate the development of effective treatments for invasive fungal infections.
