Follicle Mite

 

(Demodex folliculorum), a mite that is parasitic in the cutaneous glands and hair follicles of man and mammals. The body is elongated (0.3-0.38 mm). The mite has piercing mouthparts and four pairs of very short legs; the posterior section is extended and striated transversely. In man, the follicle mite is parasitic in healthy skin (hair follicles, sebaceous glands of facial skin and auditory meatus, and meibomian glands) without betraying its presence. The view that the follicle mite causes blackheads lacks adequate proof. In animals, the mite causes the disease called demodicosis.
