Demodicidosis: historical review

Publication date: 26/09/2016

Demodectic eruptions (demodicidosis) are the infestation of hair follicles of the skin of many animals and also humans caused by mites of the family Demodicidae. A historical review of the disea- se is made, from 1841 –with the discovery of these mites called Demodex by Simon– to this day. The relationship of Demodex with rosacea is commented, and thoughts and opinions about this entity based on observations of the authors are included.

Not to give the importance they deserve the Demodex as etiologic agents of rosacea, and unless you study the better your associations with bacteria and resistance to antibiotics and the interaction of humans and animals, we will continue without understanding, and without controlling the disease, which we should call, as described by the authors Ayres in the decade of the sixties, "pityriasis folliculorum (Demodex)" and acne rosacea (Demodex type) or, more simply, "demodicidosis in humans." It should also be considered in the books of dermatology as an ectoparasitosis and stop thinking that the Demodex are only flora normal microbiota of skin
