Symptoms are variable and include hemorrhagic diarrhea, although constipation has been recorded. The animals walk stiffly with an arched back, have shallow respiration and a weak rapid pulse. They become prostrate and comatose before death. Insertion of a stomach tube and administration of intestinal protectives are suggested in severe diarrhea. If constipated, give mineral oil by the same route.
Intravenous fluids are helpful in dehydrated animals.
