MAIN EDUCATIONAL POINTS from G211

  1. Along with clinical symptoms, a properly prepared, stained, read and reported gram stain will provide information to aid the clinician in distinguishing between colonization and infection – prompt reporting allows for initiation of appropriate treatment while waiting for culture results.
  2. Neutrophils are commonly observed in gram stains, especially from infected wounds. Their presence is an indicator of an active inflammatory process, useful in assessing the clinical significance of isolates.
