Figure 2: Photomicrograph showing spiral cork-screw shaped organisms (a – H and E, b – Giemsa stain, c – Warthin Starry stain). (d) - Pseudopyloric metaplasia (long arrow), intestinal metaplasia highlighted by AB-PAS (short arrow, inset), lymphoid aggregate (star). (e) - Immunohistochemistry for H. pylori showing positivity with knob-like pattern. (e, inset) - Metaplastic epithelium showing colonization by the bacteria. (f) - Deeper tissue invasion by the organism. (f, inset) - Organism within the lumen
