BACTERIAL INFECTIONS

Bacterial Skin Infections

Humans are natural hosts for many bacterial species that colonize the skin as normal flora. Staphylococcus aureus and Streptococcus pyogenes are infrequent resident flora, but they account for a wide variety of bacterial pyodermas. Predisposing factors to infection include minor trauma, pre existing skin disease, poor hygiene, and, rarely, impaired host immunity.

The most common bacteria to cause skin infections are:

  • Folliculitis
  • Furunculosis (boils) and abscesses
  • Impetigo (school sores) and ecthyma
  • Cellulitis
  • Erysipelas
  • Impetigo
