The name of the condition derives from ancient Greek μυῖα ( myia), meaning "fly". tenax can cause in humans via water containing the larvae or in contaminated uncooked food. There can also be accidental myiasis that E. Some flies lay eggs in open wounds, other larvae may invade unbroken skin or enter the body through the nose or ears, and still others may be swallowed if the eggs are deposited on the lips or on food. Such variations depend largely on the fly species and where the larvae are located. Myiasis varies widely in the forms it takes and its effects on those affected. Although typically a far greater issue for animals, myiasis is also a relatively frequent disease for humans in rural tropical regions where myiatic flies thrive, and often may require medical attention to surgically remove the parasites. Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species (including the most common myiatic flies-the botfly, blowfly, and screwfly) can create an infestation even on unbroken skin and have been known to use moist soil and non-myiatic flies (such as the common housefly) as vector agents for their parasitic larvae.īecause some animals (particularly non-native domestic animals) cannot react as effectively as humans to the causes and effects of myiasis, such infestations present a severe and continuing problem for livestock industries worldwide, causing severe economic losses where they are not mitigated by human action. s ə s/ my- EYE-ə-səss ), also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae ( maggots) that grow inside the host while feeding on its tissue.

Sheep scab is caused by a tiny, pearly-white mite ( Psoroptes ovis). The mite can survive off the sheep for 16 to 18 days on items like gate posts, trailers and fencing posts, hence a 21 day isolation period is advised. In all cases, a closed flock will prevent the disease entering the farm. New sheep entering a flock should be dipped and isolated from the rest of the flock.
