→Clincal Signs
The initial diagnosis of enterotoxaemia is made on the basis of history of sudden deaths in well-grown, unvaccinated lambs fed on a carbohydrate rich diet, supported by post-mortem finsings. Positive ELISA rtest results for identification of toxins in intestinal contents or peritoneal fluid support, but do not confirm the diagnosis because iimmune animals may have high concentrations of toxin but not suffer from its effects. The diagnosis can be confirmed by brain histopathology.

Affected lambs are usually less than two weeks old, but sporadic suffen death of stronger single lambs does occur. Lambs may be seen with acute abdominal pain but die within four hours. Faeces are usually normal, but can be semi-fluid and blood stained.
Lamb dysentery is an acute disease of lambs <3 wk old. Many may die before signs are seen, but some newborn lambs stop nursing, become listless, and remain recumbent. A fetid, blood-tinged diarrhea is common, and death usually occurs within a few days
