Demodex folliculorum is a microscopic mite that can survive only on the skin of humans. 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; but they can cause disease, known as demodicosis.
Demodex. Demodex / ˈdɛmədɛks / is a genus of tiny mites that live in or near hair follicles of mammals. Around 65 species of Demodex are known. [2] Two species live on humans: Demodex folliculorum and Demodex brevis, both frequently referred to as eyelash mites, alternatively face mites or skin mites.
Demodicosis. Demodicosis / ˌdɛmədəˈkoʊsɪs /, also called Demodex folliculitis in humans [1] and demodectic mange ( / dɛməˈdɛktɪk /) or red mange in animals, is caused by a sensitivity to and overpopulation of Demodex spp. as the host's immune system is unable to keep the mites under control.

Mites are tiny members of the class Arachnida; most are in the size range 250 to 750 μm (0.01 to 0.03 in) but some are larger and some are no bigger than 100 μm (0.004 in) as adults. The body plan has two regions, a cephalothorax (with no separate head) or prosoma, and an opisthosoma or abdomen.
List of mites associated with cutaneous reactions. Many mites can bite human skin and cause cutaneous reaction and/or disease. Mites which cannot bite humans may also transmit disease or cause allergies.
Acariasis 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 and severe itching sensations. An example of such an infection is scabies or gamasoidosis .
Ornithonyssus bacoti (also known as the tropical rat mite and formerly called Liponyssus bacoti) is a hematophagous parasite. [1] It feeds on blood and serum from many hosts. [2] [3] O. bacoti can be found and cause disease on rats and wild rodents most commonly, but also small mammals and humans when other hosts are scarce.
Mange ( / ˈmeɪndʒ /) 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.
Most fungus gnats are weak fliers, and can often be seen walking rapidly over plants and soil, rather than flying. However, when airborne, the gnats may be quite annoying to humans by flying into their faces, eyes, and noses, both indoors and outdoors. These flies are sometimes confused with drain flies.
