==Ulcerative Enteritis==
* Ulcerative enteritis is relatively uncommon.
* Very severe lesions pentrate through the mucosa, producing haemorrhage and death, e.g.
** In dogs with a mast cell tumour.
** In [[Bovine Viral Diarrhoea Virus|bovine viral diarrhoea-mucosal disease]].
** In some bacterial diseases
*** e.g. Salmlonellosis
**** Salmonella typically produces a broad spectrum of disease.
**** Classically may produce 'button' ulcers, especially in the terminal small intestine and upper large intestine (Ileocaecocolic junction).
***** Seen particularly in [[Salmonella|Salmonella cholerae suis]] in the pig.
==[[Classical Swine Fever]]==
==Cyathostomosis==
* In the horse.
* Small strongyles.
* 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.
