Related to demodectic mange: sarcoptic mange
an infestation of the hair follicles and sebaceous glands with mites of the genus Demodex; occur in humans and several species of domesticated animals; although asymptomatic in most species, these mites can cause severe and extensive dermatitis ("red mange") in dogs. See: Demodex.
mange which in all species is caused by species-specific Demodex spp. Characterized by folliculitis with hair loss and often pustule formation anywhere on the body although the head, face, neck and shoulders are most often affected. The cause of wastage due to the disease in large animals, mainly cattle, goats and pigs, is the reduced value of the hide or pelt.
The disease is most common in dogs where it is associated with an abnormality of cell-mediated immunity. Most often, there are one or a few areas of hair loss in young dogs (localized) which will heal spontaneously, although treatment is often given. Occasionally the disease is generalized, severe and resistant to all treatment. Examination of a skin scraping confirms the diagnosis. Called also follicular mange, red mange, demodicosis.
