A genus of very minute (0.1–0.4 mm) follicular mites (family Demodicidae) that inhabit the skin and are usually found in the sebaceous glands and hair follicles of mammals, including humans. Some cases of blepharitis in humans have been attributed to D. infection; use of facial creams promotes D. infection in older women, resulting in facial erythema with follicular scaling. [G. demos, tallow, + dex, a woodworm]
- D. folliculorum a very common, universally distributed, and usually nonpathogenic species of mite that inhabits the hair follicles and sebaceous glands of humans, commonly of the face around the nose and scalp margins. SYN: Acarus folliculorum.
