The Skin and Infection

Normal, healthy skin presents a natural physical barrier to bacterial invasion. An intact stratum corneum layer provides a barrier to a wide variety of bacteria and other pathogens. The natural resistance of the skin to bacterial penetration and multiplication is not completely understood, but elements involved include the following factors[1]:

  • Inability of organisms to penetrate the keratinized stratum corneum;
  • Desquamation, which sheds bacteria as it sloughs keratinocytes;
  • Natural acidity of the skin (pH 5.5);
  • Presence of antibacterial substances in sebaceous secretions and intracellular lipids of the stratum corneum;
  • Relatively low moisture content of skin; and
  • Normal cutaneous microflora.

Changes in any of these factors can greatly influence an individual's susceptibility to infection, as can changes in the overall ability of the host to mount an inflammatory response. Nonpathogenic microbes are capable of becoming disease-producing pathogens in individuals with reduced cellular or humoral defenses or defects (eg, immunocompromised or nutritionally compromised individuals).
