H. pylori specific staining. (a) Stomach biopsy (H&E, 400x) demonstrating a chronic, active inflammatory infiltrate of the lamina propria with Helicobacter pylori organisms visible along the surface of the epithelium as minute pink corkscrews (arrows). (b) Stomach biopsy (400x) with a Warthin-Starry silver stain greatly enhances the ability to visualize the Helicobacter pylori organisms along the surface of the epithelium.
