Intestinal myiasis due to Musca domestica: a report of two cases.

Abstract

Myiasis is the infestation of live human and vertebrate animals with dipterous larvae, which, at least for a certain period, feed on the host's dead or living tissue, liquid body substances, or ingested food. Intestinal myiasis is usually an accidental phenomenon, which occurs due to the ingestion of eggs or larvae present in food. Usually the patient is asymptomatic and the larvae are excreted harmlessly in the feces. In some cases, however, the passage of larvae may be associated with symptoms. The present paper describes two such cases.
