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.
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]
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 ...
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.
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
