Contact Precautions
Gram positive cocci in clusters; coagulase positive.
Can be broadly divided into health-care associated (HA) and community associated (CA).
HA-MRSA is associated with many hospital associated infections ranging from minor/severe skin and soft tissue infections to bloodstream infections and severe pneumonia. It also causes many device associated infection and prosthetic infections.
CA-MRSA is associated with skin and soft tissue infections (e.g. abscesses) and necrotizing pneumonias. However, it can also cause many severe infections as with HA-MRSA.

Oxacillin/cloxacillin resistant S.aureus are considered resistant to other b-lactam agents, ie, penicillins, b-lactam combination agents, cephalosporins (with the exception of the cephalosporins with anti-MRSA activity that are not available in Canada) and carbapenems. (CLSI m100-28)
