title: [Accidental myiasis by Ornidia obesa in humans].
abstract: Dipterous of the genus Ornidia are pollinator bugs, but immature stages can be found in organic matter in decomposition. This article refers to a found of larvae of Ornidia obesa in humans feces. An eight years old child was treated in a medical clinic due to the presence of two larvae and one pupae in the feces, hyperthermia, intestinal obstruction and strong abdominal pain. Medical therapy consisted of Mebendazol and Ivermectin in the indicated doses. 24 hours after the administration of the drugs, several larvae were expelled with diarrheic feces. The material was taken to the Parasitological Veterinary Lab, and the larvae were classified belonging to the genus Ornidia. According to the literature, this specie of Diptera is not incriminated to cause myiasis in vertebrates. We think that this study reports a case of accidental myiasis in humans, were the patient may have ingested food with immature stages of the fly (eggs or larvae).
