Staphylococcus aureus bacteremia without a localizing source in pediatric patients.

Staphylococcus aureus bacteremia without a localizing source in children is not well described. We identified patients with a positive blood culture for S. aureus from an 11-year surveillance study. Thirty-six cases of primary bacteremia were identified accounting for 5.7% of bacteremias. Most patients had comorbidities (86.1%), most commonly immunosuppression (33.3%).
