  • Title: Cryptococcus neoformans Virulence Assay Using a Galleria mellonella Larvae Model System.
    Author: Stempinski PR, Smith DFQ, Casadevall A.
    Journal: Bio Protoc; 2022 Aug 05; 12(15):. PubMed ID: 36082366.
    Abstract:
    Cryptococcus neoformans is a human pathogenic fungus that can cause pulmonary infections and meningitis in both immunocompromised and otherwise healthy individuals. Limited treatment options and a high mortality rate underlie the necessity for extensive research of the virulence of C. neoformans . Here we describe a detailed protocol for using the Galleria mellonella (Greater Wax Moth) larvae as a model organism for the virulence analysis of the cryptococcal infections. This protocol describes in detail the evaluation of G. mellonella larvae viability and the alternatives for troubleshooting the infection procedure. This protocol can be easily modified to study different inocula or fungal species, or the effects of a drug or antifungal agent on fungal disease within the larvae. We describe modified alternative versions of the protocol that allow using G. mellonella to study fungal diseases with different inocula and at different temperatures.
