Laboratory Evidence of the Presence of Demodex in Urine Laboratory: A Case Report

Abstract

Folliculorum mites (Demodex folliculorum, and D. brevis) are part of the common external parasites in humans as the exclusive host of them. The highest focus of these mites is on those parts of the body that have fat glands and fatty products in the skin. This is proven by the dermal – epidermal separation method. In the present study, the presence of Demodex is reported in a urine sample containing hematuria, which has not been observed so far according to the previous investigations. The case was related to a 44-yr-old woman with symptoms of headache, chills, and joint pain referring to the medical diagnostic laboratory of Sanandaj, Kurdistan Province, northwest of Iran. After historiography and collecting the urine sample as middle, the live parasite of Demodex was observed. The presence or migration of mite in the atypical areas of the body (genital, urinary, eye, etc.), which are close to hairy tissues (especially in women), may be one of the causes of allergic reactions and clinical symptoms in people.
