Aspergillus can break down a specific sugar, cellobiose, into two glucose molecules, while most other microbes and human cells cannot. The researchers developed a radioactive version of cellobiose which when injected in the blood, it can be visualized in the body using positron emission tomography (PET) scanners.In this study [<a href="https://www.science.org/doi/10.1126/scitranslmed.adl5934">published in Science translational Medicine</a>], radioactive cellobiose ([18F]-Fluorocellobiose, [18F]-FCB) was injected in mice with fungal infections which were then imaged using a specialized PET scanner for small animals. The mice showed accumulation of radioactivity, while mice with bacterial infections or with noninfectious inflammation did not.Researchers also found that the same radioactive tracer, [18F]-FCB, can determine if the mice with fungal infections are responding to treatment through PET images taken before and after starting treatment.The study was funded by the Center for Infectious Disease Imaging (CIDI), a joint initiative between Radiology and Imaging Sciences (RIS) at the NIH Clinical Center and the National Institute of Allergy and Infectious Diseases (NIAID), in collaboration with the Chemistry and Synthesis Center (CSC) at the National Heart, Lung and Blood Institute (NHLBI).This <a href="https://www.nih.gov/news-events/news-releases/new-imaging-method-detects-fungal-infections-caused-aspergillus-fumigatus-sooner">news release</a> was published by the National Institutes of Health on August 14, 2024.</div></body>
