G142

Gram – Wound: Gram negative bacilli, gram positive cocci in chains, gram positive bacilli, few neutrophils  – Shipped August 2014

HISTORY

A simulated foot ulcer drainage smear collected from a 73 year old diabetic patient was sent to category A, B, C, and C1 laboratories for Gram staining.

Participants were expected to report the presence of neutrophils, gram negative bacilli, gram positive cocci, and gram positive bacilli.

MAIN EDUCATIONAL POINTS from G142

  1. Diabetic foot infections are often polymicrobial, often involving obligate anaerobes in addition to Staphylococcus aureus, β-hemolytic streptococci, and gram negative aerobic rods
  2. Correlation of the Gram stain with the culture results is of great importance.
