Helicobacter felis ‐Associated Acute Gastric Mucosal Lesion: Ultrastructure by Low‐Vacuum Scanning Electron Microscopy
Year: 2026
Type: article
Study design: Case Report
Abstract: This report describes a rare case of acute gastric mucosal lesion associated with H. felis infection. Numerous bacilli were identified within the mucopurulent exudate. The microorganisms were larger, longer, and more tightly coiled than H. pylori. Low vacuum-SEM reveals the spiral microorganisms with characteristic two or three periplasmic fibrils on the surface. RT-PCR detected the presence of H. felis urease B gene.
