![]() ![]() ![]() Although any exposed human surface may be involved in myiasis, intact or damaged skin, eyes, nose, ears, brain, scalp, and uro-genital tract can also be involved 9. Larvae then develop after 4-8 days and transform into the adult fly after 6-14 days 7,8. The eggs transform into a conical larva between 8-12 hours and complete peritreme of posterior respiratory spiracles. Their life cycle is 2 to 3 weeks, but it may be shorter in summer. Although they are usually known as sheep blowfly, they do not have host specificity. Dermis and wounds are the most common sites of parasitism. The adult Lucilia fly has a metallic-green or copper green color with a diameter of 8-10 mm and is seen around butcher shops and slaughter houses. The Calliphorinae contain Lucilia, Calliphora, Cordylobia and Auchmeromyia genuses. The Calliphoridae family is divided into two subfamilies as Calliphorinae and Chrysomya. They cause myiasis in humans and domestic herbivorous animals. The genus of Lucilia blowfly is obligatory and/or facultative ecto-parasites that belong to Calliphoridae family and are found in meat and animal corpses. The classification of myiasis is based on larvae location on the host body or according to the type of host– parasite relationship (obligatory, facultative or pseudomyiases) 2. Myiasis is a common parasitic infestation in the tropics and subtropics but rare outside the endemic regions. The extent of the disease depends on the fly species responsible for the disease and the host immune response 6. Larvae hatched from the eggs can affect cutaneous tissue, body cavities and body organs 5. The fly may also drop its eggs while in flight on the skin, wounds or natural openings. Myiasis is the invasion of live mammalian tissue by the larvae of diptera flies for feeding on the host organs and body fluids. ![]()
