Pathogenesis (disease development)
Impetigo contagiosa is an infection with Staphyloccocus aureus, less commonly Streptococcus pyogenes, one of the major representatives of GAS (group A streptococci).
Infections with Staphylococcus aureus can cause pneumonia (pneumonia), meningitis (meningitis), endocarditis (endocarditis), and even toxic shock syndrome (TSS) and sepsis (blood poisoning), in addition to skin and soft tissue infections.
Streptococcal infections can affect any region of the body, but predominantly occur on the skin and in the throat. Without treatment, streptococcal infections continue to spread in the tissue. There is usually a brownish pus present.
Onset of the disease usually after a minor trauma.
