Evaluation of Four Selective Agars and Two Enrichment Broths in Screening for Methicillin-Resistant <i>Staphylococcus aureus</i>

Abstract

To evaluate methicillin-resistant Staphylococcus aureus detection, we tested in vitro four selective agars and two enrichment broths apart and in combination. Tryptone soya broth with salt, aztreonam, and cefoxitin appeared to be the most sensitive medium. This broth was superior to a phenol red mannitol broth with aztreonam and ceftizoxime.
