→Diagnosis
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.
