H. PYLORI INFECTION Figure 13-31 H. PYLORI INFECTION Active inflammation, represented by neutrophil exocytosis between gastric epithelial cells, is often patchy in H. pylori infection and most striking at the base of gastric pits. Note the few associated lamina propria eosinophils. More about this image found in H. PYLORI INFECTION Active inflammation, represented by n...

HISTOLOGIC DETECTION OF H. PYLORI Figure 13-32 HISTOLOGIC DETECTION OF H. PYLORI A: Many basophilic H. pylori bacilli are easily identified on a routine hematoxylin and eosin (H&E) stain in the mucin adjacent to this gastric biopsy. B: A methylene blue stain is an example of a monochromatic stain, which can be used to highlight the organisms. C: A silver-based Warthin-Starry stain shows numerous small curved H. pylori bacilli, clearly visible against a counterstained background. D: An H. pylori immunoperoxidase stain confirms abundant organisms adjacent to the superficial gastric epithelium. More about this image found in HISTOLOGIC DETECTION OF H. PYLORI A: Many basophilic

ADENOVIRUS GASTROENTERITIS IN AN IMMUNOCOMPROMISED PATIENT Figure 5-16 ADENOVIRUS GASTROENTERITIS IN AN IMMUNOCOMPROMISED PATIENT A: There is nuclear enlargement, with multiple eosinophilic to basophilic enteric surface epithelial inclusions. There are indistinct nuclear membranes (“smudged” appe... More about this image found in ADENOVIRUS GASTROENTERITIS IN AN IMMUNOCOMPROMISED PATIENT A: There is nuc...

H. HEILMANNII INFECTION Figure 13-34 H. HEILMANNII INFECTION A: A methylene blue stain demonstrates two long spiraled H. heilmannii organisms (arrow) adjacent the gastric mucosa. B: H. heilmannii bacilli stain with an H. pylori immunoperoxidase stain. The organisms’ characteristic spirochetal morphology is demonstrated on this high-power view. (Courtesy of Dr. B.
