→Clinical Signs
Animals are occasionally seen alive with hyperaesthesis and ataxia, which rapidly progresses to recumbency, opisthotonus, convulsions and death. In lambs which live longer, diarrhoea and signs associated with focal symmetrical encephalomalacia can be seen.

merck Usually, sudden deaths in the best-conditioned lambs are the first indication of enterotoxemia. In some cases, excitement, incoordination, and convulsions occur before death. Opisthotonos, circling, and pushing the head against fixed objects are common signs of CNS involvement; frequently, hyperglycemia or glycosuria is seen. Diarrhea may or may not develop. Occasionally, adult sheep are affected; they show weakness, incoordination, and convulsions and die within 24 hr. In goats, the course of disease ranges from peracute to chronic, with signs that vary from sudden death to watery diarrhea with or without blood. Acutely affected calves not found dead show mania, convulsions, blindness, and death in a few hours. Subacutely affected calves are stuporous for a few days and may recover. In goats, diarrhea and nervous signs are seen, and death occurs in several weeks. Type D enterotoxemia occasionally is seen in young horses that have overeaten.
The time course from onset to death is only a few hours, so sheep are normally found dead and only occasionally seen alive.
