title: Colitis due to Dientamoeba fragilis.
abstract: Clinical reports have suggested that the parasite Dientamoeba fragilis may be a cause of acute and chronic colitis in children and adults. The mechanism by which this parasite produces colitis has not been determined. The clinical findings in this case report suggest that D. fragilis causes colitis through an invasive ulcerating process.
