Answer

Streptococcal pyoderma is treated with oral antibiotics (eg, penicillin or erythromycin) for 10 days. However, because concomitant Staphylococcus aureus infection may occur, therapy with cephalexin or cefaclor is suggested. Treatment of pyoderma may not prevent nephritis if the patient is infected with a nephritogenic strain.
