The Myiases
Human myiases can be caused by over 50 species of dipteran larvae. The numbers of human clinical myiasis reports, reflect their relative importance in the following order; cutaneous, ophthalmomyiases, nasal, oral, intestinal, ear, urogenital, and cerebral myiases. Myiasis producing flies are distributed worldwide, but most reported cases are from warm and developing countries. Molecular techniques have been applied to myiasis fly identification and classification, especially ostrids and calliphorines. Successful elimination programs have been carried out against Hypoderma spp. in the UK and Cochliomyia hominivorax in the USA, Mexico, Central America, Libya and the Caribbean Islands and another is ongoing against Crysomya bezziana in the Middle East. A beneficial myissis “Biosurgery or maggot therapy” is the intentional use of Lucilia sericata larvae applied in specially designed dressings to chronic and MRSA infected wounds. The growing larvae execration/secretion facilitate wound debridement and successfully treated leg and pressure ulcers, wounds associated with diabetes, and many other types of infected wounds in a shorter time compared to conventional treatment. Now knowledge of myiases producing flies is accepted in many countries as a forensic tool.
