The mite's gut contains potent digestive enzymes (notably peptidase 1) that persist in their feces and are major inducers of allergic reactions such as wheezing. The mite's exoskeleton can also contribute to allergic reactions. Unlike scabies mites or skin follicle mites, house dust mites do not burrow under the skin and are not parasitic. [3]
The term Acari refers to ticks and mites together, which can cause ambiguity. (Mites are a paraphyletic grouping). [citation needed] 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 ...
Magnified view of a burrowing trail of the scabies mite. The scaly patch on the left was caused by scratching and marks the mite's entry point into the skin. The mite has burrowed to the top-right, where it can be seen as a dark spot at the end. Specialty: Infectious disease, dermatology: Symptoms: itchiness, pimple-like rash [2] Usual onset
Symptoms in humans include multiple red, itchy bumps on the arms, trunk, and buttocks. Because humans are not a host for the mite, the symptoms usually go away in about three weeks. Though the medical community does not consider a human mite infestation a legitimate diagnosis, it will treat the symptoms if necessary. [8]
Mites which colonize human skin are the cause of several types of itchy skin rashes, such as gamasoidosis, [51] rodent mite dermatitis, [52] grain itch, [53] grocer's itch, [53] and scabies; Sarcoptes scabiei is a parasitic mite responsible for scabies, which is one of the three most common skin disorders in children. [54]
Demodex folliculorum is a microscopic mite that can survive only on the skin of humans. [2] [3] Most people have D. folliculorum on their skin.Usually, the mites do not cause any harm, so are considered an example of commensalism rather than parasitism; [4] but they can cause disease, known as demodicosis.
Rodent mite dermatitis (also known as rat mite dermatitis) is an often unrecognized ectoparasitosis occurring after human contact with haematophagous mesostigmatid mites that infest rodents, such as house mice, [1] rats [2] and hamsters. [3]
Grocer's itch is a cutaneous condition characterized by a pruritic dermatitis that occurs from coming into contact with mites such as Carpoglyphus passularum (a fruit mite) or Glycyphagus domesticus (a common house mite). Contact usually occurs when handling food with mites in it, such as figs, dates, prunes, grain, cheese, or other dried foods.
