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-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).
