Facultative Myiasis by Megaselia sp. (Diptera: Phoridae) in Texas: A Case Report

Abstract

Facultative myiasis caused by larval Megaselia sp. is reported in a human in Texas. On two occasions during 24 h, the youth experienced a "crawling sensation deep in [his] throat" which caused him to cough, expelling a living Megaselia sp. larva. The site of the infestation was presumed to be the sinuses or upper respiratory tract. The symptoms resolved upon expulsion of the larvae, and no additional complications were observed in the patient.
