Rounding up the usual suspects.
  • Although culture is most obvious, it's not the only way of identifying the offending agent, or monitor the progression of an infectious disease.
  • Gram stain. This is pretty obvious, but often overlooked.
    • Be suspicious of the specimen if no PMNs are present. If it's acutely inflamed there should be.
  • If you are going to culture, be sure
    • It's collected properly and
    • Transported to the lab promptly.
  • For aerobic bugs you should get
    • An identification of potential pathogens,
    • And an antibiotic sensitivity pattern.
  • Anaerobes are different case altogether.
    • They require a special transport medium.
    • Be careful of the swab, Rayon or Dacron are best
      • Natural fiber (cotton & wood) contain fatty acids that may inhibit some bugs.
    • You may have to actually send tissue.
    • Don't expect an antibiotic sensitivity panel.
