Mange (other)
Mange () is a type of skin disease caused by parasitic mites. Because various species of mites also infect plants, birds and reptiles, the term "mange", or colloquially "the mange", suggesting poor condition of the skin and fur due to the infection, is sometimes reserved for pathological mite-infestation of nonhuman mammals. Thus, mange includes mite-associated skin disease in domestic mammals (cats and dogs), in livestock (such as Psoroptes ovis, sheep scab), and in wild mammals (for example, foxes, coyotes, cougars and wombats). Severe mange caused by mites has been observed in wild bears. Since mites belong to the arachnid subclass Acari (also called Acarina), another term for mite infestation is acariasis. Parasitic mites that cause mange in mammals embed themselves in either skin or hair follicles in the animal, depending upon their genus. ''Sarcoptes'' species, spp. burrow into skin, while ''Demodex'' spp. live in follicles. In humans, these two types of mite infections, wh ...

Demodex
''Demodex'' is a genus of tiny mites that live in or near hair follicles of mammals. Around 65 species of ''Demodex'' are known. Two species live on humans: ''Demodex folliculorum'' and ''Demodex brevis'', both frequently referred to as eyelash mites, alternatively face mites or skin mites. Different species of animals host different species of ''Demodex''. ''Demodex canis'' lives on the domestic dog. The presence of ''Demodex'' species on mammals is common and usually does not cause any symptoms, although occasionally some skin diseases can be caused by the mites. ''Demodex'' is derived from Greek δημός ''dēmos'' "fat" and δήξ ''dēx'', "woodworm". Notable species ''D. folliculorum'' and ''D. brevis'' ''D. folliculorum'' and ''D. brevis'' are typically found on humans. ''D. folliculorum'' was first described in 1842 by Simon; ''D. brevis'' was identified as separate in 1963 by Akbulatova. ''D. folliculorum'' is found in hair follicles, while ''D. brevis'' lives in seb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
