- In the horse.
- Small strongyles - Cyathostomins
- L3 to L4 development in nodules in mucosa/submucosa of caecum and colon
- Can cause diarrhoea if mass emergence.
Pathology
Gross
- Encysted larvae appear as pinhead grey to red mucosal nodules.
- Mass emergence results in:
- Mucosal erosions.
- Ulcers.
- Fibrinous exudates.
- Haemorrhage.
Histopathology
- Larvae in deep mucosa/sumucosa surrounded by fibrous capsule and mixed inflammatory cells.
- Intense eosinophil, neutrophil and macrophage infiltration when larvae emerge
- May also be oedema and, if severe, mucosal ulceration.
