Archive Case #219: Contagious Caprine Pleuropneumonia

Goat veterinary case - Hard - October 8, 2026

Clinical Clues

  1. A goat keeper in East Africa calls after several animals become feverish and stop eating following the arrival of new stock.
  2. Affected goats cough and breathe painfully, standing with their elbows held away from the chest.
  3. More goats become ill over several days; the problem is spreading through the group.
  4. Ultrasound in one live goat reveals a large pleural effusion and consolidated lung.
  5. Necropsy of a herd mate that died shows severe, predominantly one-sided fibrinous pleuropneumonia with abundant pleural fluid.
  6. Species-specific PCR on that fluid identifies Mycoplasma capricolum subsp. capripneumoniae, confirming contagious caprine pleuropneumonia.
