There are several complications with the terminology:<unk>  is a term for a rash, caused by mites, sometimes with a papillae (pruritic dermatitis) or papule (papular urticaria), and usually accompanied by a hive (urticaria) and severe itching sensations. An example of such an infection is scabies or gamasoidosis. The closely related term, mange, is commonly used with domestic animals and also livestock and wild mammals, whenever hair-loss is involved. Sarcoptes and Demodex species are involved in mange, but both of these genera are also involved in human skin diseases (by convention only, not called mange). Sarcoptes in humans is especially severe symptomatically, and causes the condition scabies noted above. Another genus of mite which causing itching but rarely causes hair loss because it burrows only at the keratin level, is Cheyletiella. Various species of this genus of mite also affect a wide variety of mammals, including humans. Mite infestation sometimes implies an ectoparasitic, cutaneous condition such as dermatitis. However, it is possible for mites to invade the gastrointestinal and urinary tracts. MeSH uses the term "Mite Infestations" as pertaining to Acariformes. However, mites not in this grouping can be associated with human disease. (See "Classification", below.) The term Acari refers to ticks and mites together, which can cause ambiguity. (Mites are a paraphyletic grouping). Mites can be associated with disease in at least three different ways: (1) cutaneous dermatitis, (2) production of allergin, and (3) as a vector for parasitic diseases. The language used to describe mite infestation often does not distinguish among these.
