Pyotraumatic dermatitis
The Pyotraumatische dermatitis ( "hot spot") is a form of the surfaces pyoderma , by a localized inflammation of the superficial layers of the epidermis is characterized. It is particularly common in domestic dogs , especially animals with long, thick fur, and occurs primarily in the summer months.
The triggers are mostly harmless small skin injuries or factors that cause itching , such as flea bites, Cheyletiellose , foreign bodies, matted fur, allergies ( flea allergy , food allergy ), which through self-traumatization (itching, scratching) quickly lead to bacterial colonization and suppuration of the skin. A moist and warm skin surface promotes the growth of bacteria, which mostly belong to the normal skin flora , such as Staphylococcus intermedius . Clinically, pyotraumatic dermatitis manifests itself in a circumscribed, moist and hairless area, the surface of which has a yellowish sheen. It is accompanied by severe itching, which can lead to further traumatization of the skin and thus also to the deeper layers of the skin.
The therapy is mostly carried out locally (topically) using antibacterial shampoos or creams.
