Characteristics of skin microflora depending on duration of rosacea complicated by demodicosis

The article describes changes of the skin microflora in patients with rosacea combined with demodicosis, taking into consideration the duration of the disease. The purpose was to study characteristics of microbial skin consortium in patients with rosacea combined with demodicosis, depending on the duration of the disease. Materials and Methods. The study involved 71 patients with clinical symptoms of rosacea, combined with demodicosis, aged from 19 to 59. The experimental group included sex and age-matched patients with clinical manifestations of rosacea (68 patients), but without concomitant pathology. Results and Discussion. The microbial consortium of skin in patients with rosacea, complicated by demodicosis, was characterized by a broader species composition. The authors observed the increase in the frequency of pathogenic and opportunistic species. Genus Staphylococcus dominated in the microbiota. Their frequency and colonization rates were significantly higher than those in the controls. The number of pathogenic and opportunistic microorganisms in patients with rosacea complicated by demodicosis increased with the duration of the disease, if compared with patients without demodecosis. Conclusion. In patients with rosacea complicated by demodicosis, a broader spectrum of the microbial skin consortium was observed, if compared with the controls. With the duration of the disease the number of pathogenic and opportunistic microorganisms increased.
