Abstract

Between July 2024 and January 2025, five male patients in their early 20s to early 50s were confirmed with infective endocarditis associated with non-toxigenic in England. Three were known to have experienced homelessness. All five used non-intravenous recreational drugs. Disease progression was rapid, four patients required surgical intervention, one died. Whole-genome sequencing and multilocus sequence type (MLST) analysis identified four individuals as ST559. Clinicians and substance use services have been alerted and enhanced surveillance implemented. A prevalence study is planned.
