n. a genus of nonbloodsucking flies inhabiting lowland woods and forests of South and Central America. The parasitic maggots of D. hominis can cause a serious disease of the skin in humans (see myiasis). The maggots burrow into the skin, after emerging from eggs transported by bloodsucking insects (e.g. mosquitoes), and produce painful boil-like swellings. Treatment involves surgical removal of the maggots.
n. an infestation of a living organ or tissue by maggots. The flies normally breed in decaying animal and vegetable matter; myiasis therefore generally occurs only in regions of poor hygiene, and in most cases the infestations are accidental. Various genera may infect humans. *Gasterophilus, *Hypoderma, *Dermatobia, and Cordylobia (see tumbu fly) affect the skin; Fannia invades the alimentary canal and the urinary system; *Phormia and *Wohlfahrtia can infest open wounds and ulcers; *Oestrus attacks the eyes; and Cochliomyia invades the nasal passages. Treatment of external myiases involves the destruction and removal of maggots followed by the application of antibiotics to wounds and lesions.... myiasis
