Invasive pulmonary aspergillosis (IPA) is a highly fatal disease in immunosuppressed patients. In this study, we assessed fibered confocal fluorescence microscopy (FCFM), a new endoscopic technique that enables in vivo microscopic imaging of the distal lung, as a tool for in vivo imaging of IPA. IPA was induced in immunosuppressed rats using a wild strain of Aspergillus fumigatus (n = 6) or a fluorescent transformed TAG-RFP A. fumigatus strain (n = 10). Subpleural areas of pulmonary infection were imaged in vivo using FCFM employing a transthoracic approach. Results were compared to three immunosuppressed control groups, i.e., non-inoculated rats (n = 4), rats inoculated with sterile Phospate-buffer saline (PBS; n = 5), and rats inoculated with Geosmithia argillacea (n = 6). Only hyphae of TAG-RFP A. fumigatus were detectable both in vitro and in vivo by FCFM. In vivo, a local infiltration of fluorescent alveolar macrophages was observed with FCFM in IPA areas in all fungal infections groups, but also in focal inflammatory areas in the immunosuppressed PBS group. A specific fibrillar fluorescence was observed in IPA areas with the TAG-RFP A. fumigatus group, with a 83% sensitivity, a 100% specificity, a 100% positive predictive value and 94% negative predictive value. FCFM provides a new tool to study host-aspergillus interactions in vivo.
