Deux bacteries et une kyrielle d'infections cutanees communes.

Common bacterial skin infections represent frequent disorders encountered in general practice and in dermatology as well. They encompass a series of infections affecting the epidermis, dermis, hypodermis and subcutaneous tissues. The two main bacteria involved in these processes are Streptococcus pyogenes and Staphylococcus aureus. The resulting infections show various clinical presentations. Their management must be adapted to their gravity and to the putative or proven nature of the causal microorganism. Searching for any skin ingress possibility and any favouring factor is always of importance in order to stimulate healing and avoid recurrences. Of note, skin possibly allows the ingress way for a secondary septicemic dissemination. Conversely, skin is possibly involved in tissue localisation of septicemia.
