Pyodermitis.

Pyodermitis are primary skin infections mainly caused by pyogenic bacteria of the Staphylococcus and Streptococcus genera. They are relatively common diseases that affect adults and children. There have been frequent reports of bacterial resistance to the recommended antibiotics over the last few years; however, new substances are in use or under development, and this represents an evolution in the treatment of pyodermitis. This review aims at describing clinical, diagnostic and therapeutical features of major pyodermitis: impetigo, ecthyma, erysipelas, staphylococcal scalded skin syndrome and folliculitis.
