Objective: This study aimed to determine the prevalence and density of Demodex folliculorum and D. brevis in Erzincan Province and the association between Demodex spp. and skin moisture, pH, and temperature.


Methods: The study included total 300 healthy participants without dermatological ailments and residing in Erzincan Province. Moisture, pH, and temperature of the cheek were measured, and the presence of mite was determined in samples from the cheek, nasolabial, and chin region using the standard superficial skin biopsy technique.


Results: The prevalence and density of D. folliculorum and D. brevis were found to be 61.3% (mean 14.3/cm2) and 23.3% (mean 3.2/cm2), respectively, in healthy participants. Infestation by Demodex spp. was greater in the cheek (mean 10.4/cm2), followed by the nasolabial region (mean 7.2/cm2) and chin (mean 6.6/cm2), respectively (p<0.001). The prevalence and density of Demodex spp. were greater in those with dry skin (mean 11.6/cm2), pH of 5.5-7.0 (mean 11.2/cm2), and temperature of 20-23°C (mean 13.1/cm2). Males, with aged >60 years, with lower educational status, and who were single were significantly more infested with Demodex spp.



Conclusion: Demodex mites are very prevalent in healthy individuals with different skin moisture, skin pH, skin temperature, and demographic characteristics. This may be taken into consideration when epidemiological and clinical studies are conducted on patients having different dermatological ailments.
