Organisms in the Upper Gastrointestinal Tract: A Report of 3 Cases With Varying Presentations.

species are anaerobic gram-positive cocci rarely seen in the upper gastrointestinal tract and associated with delayed gastric emptying. We present 3 cases of infection with varying clinical presentations including the first reported case of in a patient with eosinophilic esophagitis. Although the pathogenesis of is unclear, awareness of the bacteria is important as they can usually only be detected on histopathologic examination of upper gastrointestinal biopsies. Treatment in symptomatic patients may prevent severe complications such as emphysematous gastritis and gastric perforation.
