Mouse intravenous challenge models and applications.

Area of Science:

• Medical Mycology
• Infectious Diseases
• Immunology

Background:

• Murine intravenous (IV) challenge models are crucial for studying fungal infections.
• These models help investigate fungal virulence, host immune responses, and antifungal drug effectiveness.
• A well-characterized Candida albicans IV model is essential for reproducible research.

Purpose of the Study:

• To describe a standardized murine intravenous challenge model for Candida albicans.
• To outline the methodology for inducing systemic fungal infection in mice.
• To detail the procedures for preparing tissue samples for analysis of disease progression and host response.

Main Methods:

• Intravenous administration of Candida albicans cells into mice to establish systemic infection.
• Standardized protocols for fungal cell preparation and inoculation.
• Tissue sample collection and preparation from infected mice for histological and microbiological analysis.

Main Results:

• The described model allows for reproducible induction of systemic candidiasis in mice.
• Enables detailed evaluation of fungal dissemination and organ burden.
• Facilitates assessment of host inflammatory and immune cell responses to Candida albicans infection.

Conclusions:

• The Candida albicans IV challenge model provides a robust platform for studying systemic fungal infections.
• This model is valuable for preclinical evaluation of antifungal therapies and understanding host-pathogen interactions.
• Standardized methods for sample preparation are key to accurate assessment of disease and response.
