 Intestinal Myiasis -- Washington
Editorial Note: Myiasis is the infestation of live human and vertebrate animals with fly (dipterous) larvae, which, at least for a certain period, feed on dead or living tissue or ingested food of the host (1).
Intestinal myiasis occurs when fly eggs or larvae previously deposited in food are ingested and survive in the gastrointestinal tract.
Treatment of all forms of myiasis includes occlusive salves and dressings for cutaneous myiasis (7,8); manual removal of larvae in aural, genitourinary, and nasopharyngeal myiasis (7,9); application of a 15% chloroform in light vegetable oil solution (followed by manual removal) in wound myiasis (8); and administration of a mild cathartic agent in intestinal myiasis (10).
