Identification of Staphylococcus aureus from enriched nasal swabs within 24 h is improved with use of multiple culture media.

Abstract

Nasal carriage of Staphylococcus aureus is commonly evaluated via culture-based methods. We found that parallel use of two media, Baird-Parker and CHROMagar™ Staph aureus, increased detection of S. aureus from a healthy population by 29 %. We suggest use of both media for optimal identification of S. aureus from healthy cohorts.
