Practical aspects of bacterial skin infections in children.

Bacterial skin infections are a common reason for children to be examined by a pediatrician. Streptococci and staphylococci are responsible for the great majority of the infections. Because of the variety of lesions produced by these bacteria, there is support for dividing impetigo into "traditional" crusted and bullous forms. Two important forms of cellulitis--facial and periorbital--have potential for serious systemic consequences. The bacterial etiology and treatment of cellulitis, animal bites, and puncture wounds of the foot require special attention for successful outcome.
