Clinical signs and history of a closed herd plus signalment of pigs is indicative. On post mortem examination the terminal [[Small Intestine Overview - Anatomy & Physiology|small intestine]] and [[Colon - Anatomy & Physiology|colon]] are affected by proliferation of the mucosal epithelium. Signs will include thickened mucosal epithelium, polypoid-like nodules several millimetres in diameter. there may also be undifferentiated epithelium replaces goblet cells. Its appearance is almost neoplastic. <br>Histologically it will appear similar to a virus induced proliferation. Organisms seen in the apical part of epithelial cells lining glands of terminal [[Ileum - Anatomy & Physiology|ileum]], [[Colon - Anatomy & Physiology|colon]] and [[Caecum - Anatomy & Physiology|caecum]].
