Abstract

Aspergillus fumigatus is a ubiquitous fungal pathogen that forms airborne conidia. The process of restricting conidial germination into hyphae by lung leukocytes is critical in determining infectious outcomes. Tracking the outcome of conidia-host cell encounters in vivo is technically challenging and an obstacle to understanding the molecular and cellular basis of antifungal immunity in the lung. Here, we describe a method that utilizes a genetically engineered Aspergillus strain [called FLARE (Jhingran et al., 2012; Espinosa et al., 2014; Heung et al., 2015)] to monitor conidial phagocytosis and killing by leukocytes within the lung environment at single encounter resolution.
