Tissue: Bacteroides fragilis and Escherichia coli – Shipped November 4, 2019 FINAL RESULT
A simulated tissue swab sample collected from a 50 year old male diabetic with Fournier’s gangrene was sent to category A laboratories.
Participants were expected to isolate and identify Escherichia coli and Bacteroides fragilis.
MAIN EDUCATIONAL POINTS from M193-2
- Fournier’s gangrene (see below) and most intraabdominal infections are associated with both aerobic and anaerobic bacterial species that act synergistically to promote the infection.
- The anaerobic component of the infection is important (60-70%) in both tissue infections such as Fournier’s, and in intraabdominal abscesses.
