* 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.[[Category:Enteritis,_Ulcerative]][[Category:Horse]][[Category:Enteritis, Parasitic]]
