This study
was conducted to determine the prevalence and density of Demodex mites
in patients diagnosed with brucellosis. A total of 79 patients with brucellosis
(47 females, 32 males; mean age: 48.8 years) and 35 healthy controls (24
females, 11 males; mean age: 25.8 years) were included. Ethical approval was
obtained from the Erzincan University Clinical Research Ethics Committee, and
written informed consent was obtained from all participants. Biopsy samples
were collected from the cheek, nasolabial, and chin regions using the standard
superficial skin biopsy (SSSB) method, and were examined under a light
microscope for the presence and count of Demodex mites. Biopsy samples
containing ≥5 D. folliculorum and/or D. brevis were considered
positive for Demodex. The mean Demodex count per cm² was
calculated by dividing the total number of Demodex
mites by the number of Demodex-positive participants. Data were analyzed
using SPSS version 23.0 statistical software. A p-value of <0.005 was
considered statistically significant. In this study, Demodex positivity
was detected in 56 (70.9%) of the patients and in 5 (14.3%) of the controls.
Among the patients, D. folliculorum was identified in 56 cases (mean:
86.57/cm²), while D. brevis was found in 2 cases (mean: 14.00/cm²). In
contrast, among the 35 healthy controls, D. folliculorum was identified
in 5 cases (mean: 6.20/cm²), and no D. brevis was detected. Comparison
of patients and controls revealed that the differences in both prevalence and
density of Demodex spp. were statistically significant (p < 0.005).
In conclusion, similar to other patient groups, Demodex mites were found
to be highly prevalent and abundant in individuals diagnosed with brucellosis.
