M112-4

Blood: methicillin-resistant Staphylococcus aureus (MRSA) – Shipped August 2011

HISTORY

A sample simulating blood obtained from a one year old male admitted with empyema (as a complication of previous surgery) was sent to category A labs.

Participants were expected to isolate, identify, and perform susceptibility on the isolate. Laboratories were also expected to report the isolation of MRSA to infection control (IC).

MAIN EDUCATIONAL POINTS from M112-4

  1. The purpose of reporting the organism to IC is to ensure that appropriate isolation precautions are put in place.
  2. Staphylococcus aureus bacteremia is often associated with a local focus of infection that has gained access to the bloodstream and it carries increased morbidity and mortality.
