Sarcina ventriculi is a bacterium with a specific histological morphology and infection can present with symptoms such as abdominal pain, nausea, vomiting and occasionally fatal complications. Delayed gastric emptying is regarded as the most significant risk factor for infection. Its pathogenicity is currently unknown and treatment options are inconsistent. Here we report a case of gastric bezoars secondary to a mixed infection of Sarcina ventriculi and G + bacilli, which is diagnosed by a pathological biopsy.

Article Synopsis
- The study investigated exopolysaccharides from the bacterium Clostridium ventriculi, which were previously thought to be mainly cellulose, but were found to contain (1,3;1,4)-β-D-glucans.
- Researchers used the enzyme lichenase to break down these exopolysaccharides, confirming the presence of (1,3;1,4)-β-D-glucans rather than cellulose.
- Genomic analysis identified two glycosyltransferase genes (CvGT2-1 and CvGT2-2) that were shown to encode enzymes responsible for synthesizing (1,3;1,4)-β-D-glucans in yeast experiments.

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.

The bacterium (SV) is rarely identified in the upper gastrointestinal (GI) tract and has been associated with diverse clinical presentations. We aimed to characterize the clinicopathologic features of SV in the GI tract. Seventeen specimens (3 gastrectomy and 14 biopsy specimens) with histologic diagnosis of SV were identified and analyzed.
