A glycosylated 18F-fluorodeoxyglucose-derived PET tracer selectively incorporates into Staphylococcus via the glucose-specific phosphotransferase transporter and detects live gram-positive infection with >6-fold higher signal than non-infected tissue in mice.
- Why it matters: Bacterial infection is hard to distinguish from non-infectious inflammation because common PET glucose analogs reflect host immune metabolism, creating high background and limited specificity.
- What they did: The team O-glycosylated 18F-fluorodeoxyglucose to form alkyl glucosides (33–92% yield) and screened derivatives in vitro, identifying a methanol-derived β-anomer tracer with selective uptake in Staphylococcus species.
- The result: The tracer was stable in human serum, showed minimal uptake in mammalian cells and uninfected tissues, detected live gram-positive infection without accumulation in aseptic inflammation, and monitored antibiotic response in murine models.
