title: [Characteristics of the Propionibacterium strains isolated from acne patients].
abstract: Propionibacterium acnes is a component of physiological flora of human skin. It colonizes the outlets of sebaceous glands and participates in the pathogenesis of inflammatory acne. Acne vulgaris is a common skin disease. It is found in more or less exacerbated form in approximately 85% of adolescent population. The main purpose of the research was to confirm the hypothesis of Propionibacterium bacteria participation in the aetiopathogenesis of acne vulgaris. The researches have proved the presence of Propionibacterium acnes on the surface of the skin both of people with acne-related changes and these with whom such changes were not found. Statistically significant differences were found in the number of P. acnes bacteria per 1 square centimeter of healthy and disease-affected skin as well as in the diversity of biochemical types. The highest number of P. acnes bacteria have been found in fresh changes with visible symptoms of inflammation. In order to confirm the hypothesis of the participation of Propionibacterium bacteria in the aetiopathogenesis of acne, a detailed phenotypical analysis of isolated P. acnes strains have been conducted. Type, biotype, resistance pattern, proteolytic and lipolytic properties have been determined.
