Detection of Demodex species in acne vulgaris patients using different diagnostic methods

Abstract

Demodex is a permanent ectoparasite of the pilo-sebaceous units, related mainly to the facial region. Two species are specific for humans, Demodex folliculorum and D. brevis.Some of these species appear to be associated with variable skin disorders, yet controversy persists concerning this issue. Some reports indicate a connection between acne vulgaris and demodicosis. Aim of the work: to evaluate variable methods to expose Demodex mites. Patients and Methods : A total of 60 cases enrolled in the study were divided into 2 categories; 30 patients with acne vulgaris and 30 healthy volunteers. Samples were collected by three different methods: deep skin scraping, hair epilation and Scotch adhesive tape method.
