Background and purpose: 

A 30-day-old, previously healthy, near-term neonate presented with fever and swelling of the left eye. Orbital cellulitis of the left eye was diagnosed by computed tomography. Both blood culture and pus that was drained from the orbital abscess were positive for methicillin-resistant Staphylococcus aureus (MRSA), which was found to be a strain indigenous to the local community by a molecular method. Using vancomycin therapy and surgical drainage, the infant recovered uneventfully. Orbital cellulitis in neonates may rapidly progress to abscess formation, even to sepsis, and S. aureus is the most common pathogen. With the increasing prevalence of community-associated MRSA, empiric antibiotics effective against MRSA should be first considered in endemic areas.
