Mange (/ ˈ m eɪ n dʒ /) is a type of skin disease caused by parasitic mites. [1] 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.
Sarcoptic mange affects domestic animals and similar infestations in domestic fowls cause the disease known as "scaly leg". The effects of S. scabiei are the most well-known, causing "scabies", or "the itch". The adult female mite, having been fertilized, burrows into the skin (usually at the hands or wrists, but other parts of the body may ...
Symptoms may continue for two to four weeks following treatment. [13] If after this time symptoms continue, retreatment may be needed. [13] Scabies is one of the three most common skin disorders in children, along with ringworm and bacterial skin infections. [15] As of 2015, it affects about 204 million people (2.8% of the world population). [9]
This is typically caused by sarcoptic mites. Sarcoptes scabiei is an example: it infests many species of mammals, including humans. Other common sarcoptic mites are in the genus Notoedres, and the genus Knemidokoptes (or Cnemidocoptes) which infest birds.
These mites burrow into the skin of their host, causing sarcoptic mange, predominantly affecting even-toed ungulates. Pregnant female mites tunnel into the host’s stratum corneum and deposit eggs. The young mites, after hatching, move across the skin and molt into the nymphal stage, where they may harbor the bacterial pathogen Bacillus ...
Skin disease caused by sarcoptic mites is variably called scabies, or in some countries mange. [9] (The adjectives 'mangy' and 'scabby' are used similarly to 'lousy', as both a description of animals probably infested with mites or lice, respectively, and as a general expression of disgust.
Knemidocoptic mange [neʺmĭ-do-kopʹtik mānj] From the Latin manducare (to itch), mange is a skin disease caused by mites in domestic and wild animals. Knemidocoptic, from the Greek knemid (greave, a piece of armor that protects the leg) and koptein (to cut), refers to the morphology and pathogenesis of mites of the genus Knemidokoptes ...
The disease may not have spread into the west population due to the very low population densities in the areas that separate the west from the east populations (Figure 7). [8] In 2008, 56% of the whole population and 60% of the distribution range was affected by the disease. The mange is continuing to spread at the current time (2010). [3]
