[An unusual case in Belgium of intestinal myiasis due to Eristalis tenax].

We report an unusual case in Belgium of indigenous intestinal myiasis caused by Eristalis tenax during canicular summer 2003 in a 36 year old man living in Belgium. This patient complain near its general practitioner about diarrhea and intestinal rumbles. Larvae emitted on several occasions were identified as Eristalis tenax larvae. Socio-economical status of the patient and atmospheric conditions seems to be related to this observation. Clinical evolution has been spontaneously and quickly positive. An empirical treatment with an association of metronidazole and nifuroxazide was however prescribed.
