G201

Gram – Wound: 4+ (>10/oif) neutrophils, 4+ (>50/oif) gram negative bacilli (Vibrio vulnificus) – Shipped May 11, 2020 – FINAL RESULT

HISTORY

A simulated wound swab sample collected from a 36 year old male traveler with foot injury was sent to category A and C1 laboratories.
Participants were expected to report the presence of neutrophils and gram negative bacilli.

MAIN EDUCATIONAL POINTS from G201

  1. The Gram stain can provide useful initial information to clinicians, that taken in the light of other findings and the clinical history may help guide therapy.
  2. The presence of epithelial cells in the smear of a wound swab may be interpreted as indicating contamination and lessens the value of the microscopy report.
