Exudates by lung parenchymal infection

• Bacterial (parapneumonic):
  • can evolve along spectrum of exudative (but sterile) → fibropurulent (infected fluid) → organization (fibrosis & formation of rigid pleural peel).
  • Common causes:
    • Strep pneumo,
    • Staph aureus,
    • Strep milleri,
    • Klebsiella,
    • Pseudomonas,
    • Haemophilus,
    • Bacteroides,
    • Peptostreptococcus,
    • mixed flora in aspiration pneumonia.
• Mycobacterial:
  • hemogram > 50% lymphs 80% of the time,
  • ADA >40, pleural bx ~70% Se
• Fungal, viral (usually small), parasitic (eg, amebiasis, echinococcosis, paragonimiasis)
