Educational Highlights
- Immediate fixation of feces is necessary to preserve the morphology of D. fragilis as the trophozoites degenerate rapidly in unpreserved stools.
- The presence of eosinophilia in approximately 50% of patients has prompted experts to recommend that D. fragilis be included in the differential diagnosis of chronic diarrhea and eosinophilic colitis.
