|This is a picture of a tiny gastric biopsy being removed from the forceps. The biopsy can be tested for urease enzyme to detect the HP. Click here for more about the urease test.|
|This is a 3 day culture of HP on blood agar.|
|A silver stain (Warthin Starry) of HP (black wiggly things) on gastric mucus-secreting epithelial cells (x1000). This picture is notorious because it is of Dr. Marshall's stomach biopsy taken 8 days after he drank a culture of H. pylori. The experiment was published in 1985 (Marshall BJ, Armstrong JA, McGechie DB, Glancy RJ. Attempt to fulfill Koch's postulates for pyloric Campylobacter. Med J Aust 1985; 142: 436-439).|
|This is a x1000 photograph of HP in an antral gland. Ths picture and more details of the patient's history were published in the NEJM as "picture of the week". Congratulations to Drs. Bob Genta and David Graham of the Veteran's Affairs Hospital in Houston Texas.|
|This is a normal antral biopsy. It was taken from a healthy young Virginian doctor who bravely volunteered for endoscopy.|
|This is a H&E stained section of an inflamed (infected with H.pylori) gastric antral biopsy (x250). The lamina propria (area under the mucus epithelial cells) is shown. Most of the cells are lymphocytes or plasma cells (chronic inflammation). Glands may be reduced. A few neutrophils are seen invading glands (active or acute inflammation). Neutrophils are also called polymorphonuclear leucocytes because they have lobulated nuclei.|
|This is a Period Acid - Schiff (PAS) stain of duodenal mucosa. In it you can see delicate pink brush-border intestinal mucosa (bottom center) moving up to heavy gastric type epithelium (center left vertical with clear area to the left of it) then changing back to intestinal type with goblet cells and a gland at top center. The presence of the gastric type mucosa allows attachment of HP in the duodenum and subsequent development of duodenal ulcer.|
