Protostrongylus spp.

Muellerius capillaris

  • Common in sheep and goats
  • Rarely any clinical significance
  • Grossly:
    • Multifocal interstitial pneumonia grossly evident as firm "lead-shot" nodules throughout the parenchyma, often with enveloping granulomatous response
    • Early stages are reddish in colour, turning later to greyish green, may calcify
    • Mostly in dorsal region of caudal lung lobes
  • Histologically:
    • Damaged alveolar septa with mild fibrous thickening and lymphocytic infiltrate
    • In more developed host resistance, foci of eosinophils around larvae, hyperplastic epithelium, macrophages, giant cells
    • May be some calcification

Dictyocaulus filaria

  • Most susceptible when first exposed to contaminated pasture
  • Animals < 1 year old
  • Pathogenesis and pathology similar to Dictyocaulus viviparus in cattle
  • Bronchitis

In Pigs

Metastrongylus spp.

  • Found in bronchioles and smaller bronchi
  • Grossly:
    • Small grey nodules, especially along ventral border of caudal lobes
    • Adult worms in bronchi and bronchioles
  • Histologically:
    • Catarrhal and eosinophilic bronchitis and bronchiolitis
    • Possibly atelectasis
  • Rarely becomes extensive
  • May transmit swine influenza

Ascaris suum
