Linezolid resistance in rare isolates of Staphylococcus aureus has been associated with G2576T mutations in domain V of the 23S rRNA gene. We report the analysis of a clinical S. aureus isolate that developed linezolid resistance (MIC of linezolid of 12 mg/L) after a 25 day course of the drug. Sequencing identified G2576T mutations in four of the five copies of the 23S rRNA gene.
