  • Diagnosis of MRSA is established by recovery of the pathogen from the infected site
  • S aureus infection should be considered in patients with suspected pneumonia and a recent viral infection (eg, influenza), a history of injection drug use, or in those presenting with severe, bilateral, necrotizing pneumonia[CDC OI]
  • Diagnosis of pyomyositis is often made by magnetic resonance imaging[Casado 2001]
