Episode notes
S. aureus Is A Common, Versatile Pathogen
- About 30% of people carry Staphylococcus aureus, mostly MSSA but with rising MRSA presence.
- S. aureus causes diverse infections from skin abscesses to toxin-mediated GI illness and device-related infections.
Bloodstream Infection Drives Serious Complications
- S. aureus bacteremia has high mortality around 20% and tends to cause metastatic seeding.
- Common metastatic sites include heart valves, pacemakers, spine, bones, joints, lungs, brain, and skin.
Actively Pursue Source Control And Surgical Decisions
- Drain purulent collections when feasible and consider surgical intervention for infected valves causing heart failure.
- Use MRI to assess the brain before cardiopulmonary bypass if cerebral seeding is a concern.
