Abstract:   (711 Views)

Dietamoebia fragilis is protozoan parasite of the large intestine which, nulike most other ameba, has trophozoite but no cyst stage in its life cycle. How this parasite is transmitted from one host to another is still an unsolved problem; whether or not the parasite is still a matter of  debate. There is some suggestions about the role of an intestinal nematode in the its transmission.

We found an outbreak of D. fragilis infection in a family that all of 5 members were infected. They were complained a vague intermittent abdominal pain that remission and repalse were observed repeatedly. We examined stool specimens with permanent staining (with Gomori’s staining technique) and also samples inocculated to culture medium (Boeck Drbohlav’s medium) and found abundant trophozoites of D. Fragilis. With self ingestion we were not able to establish infection successfully. Repeated scotch tape examination of subjects for E. vermicularis showed ova in 4 individuals. 4 of % individuals had some sympoms intermittently, including diarrhea with mucos, abdominal pain, hungry pain, and pruritus and anorexia. Two persns had low grade esinophilia. Treatment with metoronidazole results resolution in 3 subject and 2 persons resolved without therapy, but relapse occurred and drug therapy became necessary. E. vermicularis infection eliminated with a single dose of 100mg of mebendazole. Follow up all of members not showed presence of any parasite. This findings show some evidences which support this suggestion E. vermicularis probably has an important role i D. fragilis transmission, and dietamoebiasis can occur as outbreak in the limited communities. Also we can say dietamoebiasis is a familiar disease.
