Predisposing factors

General
  • Immune incompetency, eg neoplasia.
  • Poor nutrition.
  • Unhygenic environment.
  • Anatomical factors, eg facial, lip, tail, vulvar and body folds.
  • Environmental factors, eg high temperature and humidity.
  • External trauma.
  • Viral infection.
  • Idiopathic keratinization defects.

Specific

Pathophysiology

  • Unclear.
  • Host factor +/- predisposing factor (?affecting anatomical and physiological epidermal barrier function) → penetration ofStaphylococcus intermedius Staphylococcus intermedius and its toxins into the skin → bacterial multiplication → exceed a threshold → pyoderma.
