Case of the Week

Always check the "debris." These gastric biopsies came from a diabetic patient with delayed gastric emptying. The endoscopist noted retained food in the patient's stomach. Sarcina ventriculi is present. It is not a definitive human pathogen, but it is believed to be one in ruminants, such as cows.
