Abstract
We describe two patients with chronic diarrhea associated with dysgonic fermenter-3 (DF-3) infection. One patient had common variable hypogammaglobulinemia and the other hand chronic idiopathic neutropenia and human immunodeficiency virus infection. Specific stool culture techniques were necessary to isolate DF-3. The organism was sensitive to clindamycin, tetracycline, and trimethoprim-sulfamethoxazole. Antibiotic therapy eradicated the organism and the diarrhea resolved in both patients. DF-3 is a little-recognized organism associated with diarrhea in the immunocompromised patient. It should be suspected when routine evaluation and stool cultures are not diagnostic.
