(dī'ent-ă-mē'bă fraj'i-lis),

A species of small amebalike flagellates, formerly considered a true ameba, now recognized as an ameboflagellate related to Trichomonas, parasitic in the large intestine of humans and certain monkeys; may be nonpathogenic, but believed to be capable of sometimes causing low-grade inflammation with mucous diarrhea and gastrointestinal disturbance in humans.
