DefinitionThis section has been translated automatically.
Acute or chronic infection of the epidermis (impetigo contagiosa) and possibly also of the various skin appendages (infection of the hair follicles = folliculitis; infection of the nail organs = paronychia; infection of the sweat glands = hidradenitis). This leads to pus rashes and overlapping scaling and crust formation.
A distinction is made between diseases which are called "pyoderm" and have a pyodermic appearance, but which are based on a different etiopathogenesis (e.g. Pyoderma gangraenosum).

DiagnosisThis section has been translated automatically.
Blister fluid or fresh, weeping crusts are suitable for examination. The smear material is heat-fixed and stained for methylene blue or Gram. In the Gram stain, the gram-positive cocci can be detected in cluster or grape form. Pathogen culture is usually performed on blood agar. The result can be read after 24-48h. A further differentiation can be made by means of the colored series (Api-Staph system, Api-20-Strep system).
TherapyThis section has been translated automatically.
- Benzylpenicillin is the agent of choice for infections with β-haemolytic streptococci. Alternatively, erythromycin, tetracyclines, clindamycin or cephalosporins can be used.
- For staphylococcal infections: cephalosporins or flucloxacillin (e.g. Staphylex Kps.) 3 times/day 1 g in 3 doses. Alternatively: Vancomycin, Teicoplanin, Dicloxacillin, Clindamycin, Fosfomycin.

Bacterial superinfected dermatoses are to be separated. The term impetiginization is reserved for this. However, this differentiation is not always clear.
