Blood Culture: Staphylococcus aureus (MSSA) – Shipped May 11, 2020 – FINAL RESULTS
A simulated blood culture sample collected from a 30 year old male was sent to category A laboratories.
Participants were expected to isolate and identify Staphylococcus aureus. Susceptibilities were not required for this challenge.
MAIN EDUCATIONAL POINTS from M201-4
- Bacteremia with Staphylococcus aureus is a common clinical laboratory finding. Mortality ranges between 10 to 40 percent. Higher mortality rate is associated with methicillin resistance. While delay of therapy is never desirable, on occasion, it does occur. Anti-staphylococcal therapy within 7 days of the initial positive MSSA culture was associated with survival.
