Recurrent Listeria monocytogenes aortic graft infection: confirmation of relapse by molecular subtyping.

Based on molecular typing methods, we identified a rare case of a recurrent L. monocytogenes infection resulting from an infected aortic prosthesis as detected by 18-F-Fluoro-d-deoxyglucose positron emission tomography (FDG PET). Our case highlights the usefulness of molecular typing and nuclear imaging methods for understanding L. monocytogenes pathogenesis and epidemiology.
