Inflammatory Conditions: Bacterial/ fungal/ parasitic infections

  • Usually associated with a lot of neutrophils, red cells, and lymphocytes in the background.
  • The usual suspects in these situations include:
    • Bacteria: especially gram-negative rods.
    • Fungus: most often Candida – look for budding yeast and hyphae (image A).
    • Parasites: in the U.S., the most common parasite is Trichomonas – look for teardrop shaped organism with flagella (image B); in more exotic locales, remember to keep an eye out for Schistosoma haematobium.
  • Remember: if you see lots of bugs and yeast, but no inflammation, the most likely explanation is that the specimen is contaminated.
