Porcine Enteropathy (PE)See chapter 9 for further information.
(339) In lay terms this condition is often described as bloody gut because there is acute haemorrhage into the lower part of the small intestine and, occasionally into the upper part of the large intestine (also called porcine haemorrhagic enteropathy PHE). Bloody gut is common in maiden gilts after selection or when they are moved to new premises but it can occur in pregnant gilts and very occasional in first litter lactating gilts. It would be rare to see disease in the sow. The disease is caused by a bacterium, recently named Lawsonia intracellularis, which cannot be cultured on common bacterial media but only in the living cell cultures, so your local diagnostic laboratory may not be able to confirm the diagnosis. The gilt with bloody gut may appear pale and weak with bloody or dark faeces or found dead. Post mortem examination showing massive haemorrhage in the lower intestine is strongly suggestive of this disease. PHE and its related syndromes porcine intestinal adenopathy (PIA), necrotic enteritis (NE) and regional ileitis (RI) are grouped under the heading of porcine enteropathies (PE).
