Isolation of Comamonas Species from the Stool Samples of Patients with Underlying Gastrointestinal Pathology

Comamonas species are saprophytes, thought to be rarely associated with clinical infections. We report five cases of Comamonas species associated with gastrointestinal (GI) manifestations isolated over a period of 2 years. All these patients had underlying GI pathologies like malignancy or inflammatory bowel disease. This report tends to introspect on the clinical significance of such rare pathogens in stool samples and emphasize its possible role in causing GI infections.
