# Sarcinaventriculi in association with gastric ulcer: a case report

## TL;DR

This case report describes an elderly man with a gastric ulcer linked to the presence of Sarcina ventriculi bacteria.

## Contribution

The novelty lies in reporting a specific case linking Sarcina ventriculi to a gastric ulcer in a human.

## Key findings

- Sarcina ventriculi was identified in association with a gastric ulcer in an elderly male patient.
- The patient presented with haematemesis and was diagnosed via upper gastrointestinal endoscopy.
- Histopathological examination confirmed the presence of the bacteria alongside the ulcer.

## Abstract

Sarcina ventriculi is a species of Gram-positive bacteria which has been reported in patients with delayed gastric emptying as well as in association with cases of gastric ulcer and gastric carcinoma. Although it has been reported frequently in veterinary cases as a cause of fatal diseases, the exact pathogenesis in humans has yet to be identified. We report here a case of an elderly male who presented with haematemesis following which an upper gastrointestinal endoscopy was done and a gastric ulcer was revealed. Histopathological examination revealed S. ventriculi in association with the ulcer.
