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.
The microscopic mites live in hair follicles and oil glands on the face, neck and chest, and feed on sebum and oil produced by pores. They are generally harmless, but too many can cause irritation ...

The mite parasitizes a variety of insect hosts and bites humans, causing red, itchy, and painful wheals (welts). The mites are barely visible, measuring about 0.2–0.8 millimeters; their great reproductive potential, small size, and high capacity for dispersal by wind make them difficult to control or avoid.
These mites live within the fur of cats and dogs, feeding on sloughed scales of skin. Often this causes little reaction in the host, but pruritus, seborrhea and pustules in the skin may develop as an allergic reaction to the mites. The adult mites are visible crawling in the fur and may cause similar skin reactions in the pet's owner.
Beginning in September and October, we might start to see more cases of rhinovirus (a frequent cause of the common cold) and influenza, Ellen Foxman, Ph.D., associate professor of laboratory ...

[ 17 ] Their feces include enzymes that are released upon contact with a moist surface, which can happen when a person inhales, and these enzymes can kill cells within the human body . [ 18 ]
Demodicosis / ˌ d ɛ m ə d ə ˈ k oʊ s ɪ s /, also called Demodex folliculitis in humans [1] and demodectic mange (/ d ɛ m ə ˈ d ɛ k t ɪ k /) 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. Demodex is a genus of mite in the ...
