*Acute enterotoxaemia in adult sheep, 'struck'
*Sudden death or terminal convulsions in sheep at pasture
*Beta toxin (lethal, necrotising) plays major role in pathogenesis of the disease - increases intestinal and capillary permeability
*Also alpha toxin (lecithinase)
*Post mortem: jejunal ulceration; hyperaemia in small intestine; fluid accumulation in peritoneal cavity; congestion of peritoneal vessels; petechial haemorrhages
*Haemorrhagic enteritis in piglets
**Peracute enterotoxaemia often of entire litter with mortality rates 80%
**Infection from sow's faeces
**Death within 24 hours in young piglets
**Chronic disease in older piglets
**Dullness, anorexia, bloody faeces, perianal hyperaemia
**Post mortem: necrosis of terminal small intestinal mucosa, caecum and colon and blood-stained contents; serosanguinous fluid in pleural and peritoneal cavities
*Necrotic enteritis in chickens:
**Broilers under 12 weeks
**Acute enterotoxaemia, sudden onset and high mortality
**Necrosis of small intestine
**Predisposing factors include diet changes, coccidial infection and intestinal hypomotility
*Acute enterotoxaemia with haemorrhagic enteritis in calves, lambs, foals, goats
*[[Peritoneal Cavity Inflammatory - Pathology#In cattle|Peritonitis in cattle]] - sudden death in feedlot cattle
