PROPIONIBACTERIUM ACNES AND THE SKIN DISEASE OF ACNE VULGARIS. PROPIONIBACTERIUM ACNES SI IMPLICAREA LUI IN ACNEEA VULGARA
Abstract 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 ora, 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. Key words: Propionibacterium acnes, Acne vulgaris, skin colonization Rezumat Pielea gazduieste o varietate de microorganisme care participa la alcatuirea microflorei cutanate. Bacteriile si fungii par a fi pionierii florei cutanate normale. Particularitatile anatomice si diferite conditii zico chimice in uenteaza demogra a populatiilor microbiene. In cadrul diferitelor tipuri de populatii microbiene, Propionibacterium Acnes se gaseste predominant in pielea de la nivelul fetei si al toracelui antero posterior. Desi aceasta bacterie face parte din flora cutanata normala, Propionibacterium Acnes este de asemenea responsabila de aparitia acneei. Dezvoltarea unor discipline stiintifice precum Microbiologia, Genetica si Biologia Moleculara, va concluziona daca anumite tulpini de Propionibacterium Acnes sunt utile si benefice iar altele sunt daunatoare. Asadar, in revizuirea de fata, autorii analizeaza diferite caracteristici ale P. Acnes si implicarea in acneea vulgara.
