Abstract:
Invasive fungal infections comprise a group of serious and life-threatening diseases affecting immunocompromised patients. Molecular analysis of fungal virulence involves the deletion of genes that are suspected for contributing to fungal pathogenesis. Phenotypic analysis of the generated mutants includes in vivo infection experiments in order to assign a function during fungal disease to a gene of interest.
Insights
Researchers study invasive fungal infections by deleting genes in fungi to understand how they cause disease. This helps identify key virulence factors in dangerous infections affecting immunocompromised individuals.

- Molecular genetics provides tools to dissect the mechanisms of fungal pathogenesis.
Purpose of the Study:
- To investigate the role of specific genes in fungal virulence.
- To identify novel targets for antifungal therapies.
Main Methods:
- Gene deletion in fungal pathogens.
- Construction and characterization of fungal mutants.
