Community-associated methicillin-resistant Staphylococcus aureus necrotizing fasciitis in a neonate.

Neonatal necrotizing fasciitis is rare and is predominantly associated with methicillin-susceptible Staphylococcus aureus (MSSA). Necrotizing fasciitis associated with community-associated methicillin-resistant S aureus (CA-MRSA) has only recently been reported in the literature, primarily among adults. We present a case of a previously healthy neonate with necrotizing fasciitis of the back caused by CA-MRSA, pulsed-field type USA-300. We describe a 5-day-old infant with necrotizing fasciitis of the back caused by CA-MRSA. Treatment of necrotizing fasciitis requires prompt medical evaluation, prompt surgical debridement, and appropriate antibiotic selection. The potential involvement of CA-MRSA in necrotizing fasciitis in children needs to be considered before institution of antibiotics.
