WHAT ARE SKIN AND SOFT-TISSUE INFECTIONS?

  1. 1
    WHAT IS THE MEANING OF SKIN AND SOFT-TISSUE INFECTIONS?
    • Bacterial infections of the skin can be classified as primary or secondary (Table 1–1). Primary bacterial infections are usually caused by a single bacterial species and involve areas of generally healthy skin (e.g., impetigo and erysipelas). Secondary infections, however, develop in areas of previously damaged skin and are frequently polymicrobial.

    • The conditions that may predispose a patient to the development of skin and soft-tissue infections (SSTIs) include (1) a high concentration of bacteria; (2) excessive moisture of the skin; (3) inadequate blood    supply; (4) availability of bacterial nutrients; and (5) damage to the corneal layer, allowing for bacterial penetration.
    • The majority of SSTIs are caused by gram-positive organisms and, less commonly, gram-negative bacteria present on the skin surface. Staphylococcus aureus and Streptococcus pyogenes account for the majority of SSTIs. Community-associated methicillin-resistant S. aureus (CA-MRSA) has emerged and is often isolated in otherwise healthy patients.
