Staphylococcus aureus

Background

Staphylococcus aureus is the main coagulase-positive staphylococcus, a gram-positive bacteria
Sub-types are:

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]
