Nasal Staphylococcus aureus colonization among mothers of term and late preterm previously healthy neonates with community-acquired Staphylococcus aureus infections.

ABSTRACT

We enrolled 35 case neonates with community-acquired Staphylococcus aureus infection and their mothers and 19 control mother-neonate pairs. We obtained neonatal and maternal anterior nasal cultures, and clinical isolates. S. aureus nasal colonization was greater in case than control pairs. Neonates were more often infected with their nasal strain than their mother's nasal strain.
