This bacteria is a gram-positive, anaerobic, rod- shaped, motile, spore-forming bacillus that causes botulism. There are several kinds of botulism: food-borne botulism, infant botulism, wound botulism, adult intestinal toxemia, iatrogenic botulism and inhalational botulism. Symptoms of infection may include: double vision, blurred vision, drooping eyelids, slurred speech, difficulty swallowing, dry mouth, and muscle weakness. These symptoms are caused by the neurotoxin botulinum. If the disease condition is untreated, symptoms may progress to cause paralysis of the respiratory muscles, arms, legs, and trunk.
