Molecular investigation of unexpected Helicobacter pylori bacteremia.

Abstract

This study describes the isolation of Helicobacter pylori from a blood sample of an 88-year-old patient with no history or clinical signs suggestive of this infection. We summarize the microbiological characterization of the case, and the subsequent investigation using advanced next-generation sequencing methods, including a target enrichment technique adapted for paraffin-embedded gastric biopsy analysis.
