Skin infection

Definition
This 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).

Diagnosis

Bladder fluid or fresh, weeping crusts are suitable for examination. The smear material is heat-set and stained according to methylene blue or gram. Gram staining allows the detection of Gram-positive cocci in heaps or grapes. The pathogen culture is usually carried out on blood agar. The result can be read off after 24-48h. A further differentiation can be made by means of the coloured row (Api-Staph system, Api-20-Strep system).
