Psoriasis is a chronic noninfectious and inflammatory skin disease, whose pathogenesis involves environmental triggers, including microbiota. In our study we compared bacterial composition between healthy controls and psoriatic patients using V1V2 hypervariable region of 16S rRNA. We found higher species diversity in psoriatic lesions than in contralateral psoriatic healthy site or in healthy control skin. Genus Propionibacterium was more abundant in contralateral healthy sites (57.77%) than in affected psoriatic sites of psoriatic patients (47.12%). On the other hand, we found higher abundance of genus Staphylococcus in psoriatic lesions (18.78%), while lower abundance in contralateral healthy sites (9.52%). Since Propionibacterium are commensal bacteria, the shift in their abundance from healthy to psoriatic skin could be due to disturbation of natural skin habitat. Interpretation of higher presence of Staphylococcus in psoriatic lesions comparing to contralateral healthy sites requires further species characterization. To complete the picture about psoriatic microbiome we will further investigate skin fungal composition in identical samples.
