*Grossly:

−

**Firm yellow nodules scattered throughout parenchyma, more frequently at periphery

−

*Microscopically:

−

**Eggs and larvae in the alveolar spaces cause a foreign body type reaction (surrounded by mononuclear cells and giant cells)

−

**Submucosal gland hypertrophy and smooth muscle hypertrophy in airway and vessel walls

−

*Associated clinical signs are mild although heavy infestations may -> chronic coughing

−

*The airway eosinophilia which may be detected can be confused with a diagnosis of asthma
