PROPIONIBACTERIUM ACNES AND THE SKIN DISEASE OF ACNE VULGARIS.

The human skin encompasses a vast variety of microorganisms which construct the structure of skin microflora. Bacteria and yeasts may be the pioneers of the human skin normal flora. The anatomical situations and physicochemical conditions determine the demography of the microbial populations. Among different types of microbial populations, Propionibacterium acnes is the predominant member in the skin areas of back, face and chest. Although this bacterium is part of the normal flora, Propionibacterium acnes contributes to the disease of acne vulgaris. By the progression of scientific disciplines such as Microbiology, Genetics, and Molecular Biology, it is going to be clear that some strains of Propionibacterium acnes are useful and good bacteria and some strains are harmful and bad bacteria. Therefore, in this review, the authors have a look on different characteristics of P.acnes and the related skin disease of acne vulgaris. [ABSTRACT FROM AUTHOR]
