Mindful diagnostics in culture-negative endocarditis: early noninvasive diagnosis of Tropheryma whipplei by plasma microbial cell-free DNA

Abstract:
Tropheryma whipplei was identified by plasma microbial cell-free DNA sequencing within 4 days in severe culture-negative endocarditis after antibiotics had already been started. The result supported earlier diagnostic clarification and antimicrobial de-escalation before valve pathology was available, illustrating a practical diagnostic-stewardship role for noninvasive sequencing in high-acuity endocarditis.
