The diagnosis of fungal infections is difficult, lacking specificity and sensitivity. This review covers findings on the preclinical use of siderophores for the molecular imaging of infections. Siderophores are low molecular mass chelators produced by bacteria and fungi to scavenge the essential metal iron. Replacing iron in siderophores by radionuclides such as gallium-68 allowed the targeted imaging of infection by positron emission tomography (PET). The proof of principle was the imaging of pulmonary Aspergillus fumigatus infection using [68Ga]Ga-triacetylfusarinine C. Recently, this approach was expanded to imaging of bacterial infections, i.e., with Pseudomonas aeruginosa. Moreover, the conjugation of siderophores and fluorescent dyes enabled the generation of hybrid imaging compounds, allowing the combination of PET and optical imaging. Nevertheless, the high potential of these imaging probes still awaits translation into clinics.<\/jats:p>","DOI":"10.3390\/jof6020073","type":"journal-article","created":{"date-parts":[[2020,6,1]],"date-time":"2020-06-01T11:49:21Z","timestamp":1591012161000},"page":"73","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":48,"title":["Siderophore-Based Molecular Imaging of Fungal and Bacterial Infections\u2014Current Status and Future Perspectives"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1334-5916","authenticated-orcid":false,"given":"Milos","family":"Petrik","sequence":"first","affiliation":[{"name":"Institute of Molecular and Translational Medicine, Faculty of Medicine and Dentistry, Palacky University, 77900 Olomouc, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5357-126X","authenticated-orcid":false,"given":"Joachim","family":"Pfister","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Medical University Innsbruck, 6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6380-700X","authenticated-orcid":false,"given":"Matthias","family":"Misslinger","sequence":"additional","affiliation":[{"name":"Institute of Molecular Biology, Medical University Innsbruck, 6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0566-4036","authenticated-orcid":false,"given":"Clemens","family":"Decristoforo","sequence":"additional","affiliation":[{"name":"Department of Nuclear Medicine, Medical University Innsbruck, 6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2472-9878","authenticated-orcid":false,"given":"Hubertus","family":"Haas","sequence":"additional","affiliation":[{"name":"Institute of Molecular Biology, Medical University Innsbruck, 6020 Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"509","DOI":"10.1016\/j.chom.2013.04.010","article-title":"Iron in infection and immunity","volume":"13","author":"Cassat","year":"2013","journal-title":"Cell Host Microbe"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1213","DOI":"10.1084\/jem.20041242","article-title":"Siderophore biosynthesis but not reductive iron assimilation is essential for Aspergillus fumigatus virulence","volume":"200","author":"Schrettl","year":"2004","journal-title":"J.
