Shewanella spp. infection following treatment for upper gastrointestinal bleeding.

Shewanella spp. are an uncommon cause of human infection, with exposure to water being the commonest source. We report a patient with a malignancy and upper gastrointestinal bleeding who underwent a gastric lavage followed by an endoscopy as part of her investigations. She subsequently developed Shewanella spp. bacteraemia without any clinical source of infection.
