Staphylococcus aureus


  • Staphylococcus aureus is the main coagulase-positive staphylococcus, a gram-positive bacteria
  • Sub-types are:
    • Staph. aureus MSSA
    • Staph. aureus MRSA
    • Staph. aureus CA-MRSA
  • Always consider a blood culture positive for Staphylococcus aureus to be true bacteremia (and not a contaminant) due to the danger of delaying treatment[1]
