Botulism: Clinical Features, Laboratory Insights and Management Options

Abstract

Botulism is a neuroparalytic disease caused by the neurotoxin produced by Clostridium botulinum (a gram-positive, anaerobic, endospore-forming bacillus). Botulinum neurotoxin (BoNT) is one of the most potent substance known, and seven toxin serotypes (serotypes A–G) have been identified. Type A serotype botulism is the most common cause of human botulism, and can occur in epidemics. Botulism occurs ingestion of food contaminated with BoNT, colonization of a wound by neurotoxin-producing Clostridium species, exposure to botulinum neurotoxins by inhalation or injection. All forms of botulism, progressive muscle weakness is usually seen, begins in the cranial nerves and progressing from proximal to distal to the extremities. This descending paralysis can lead to respiratory failure and death with involvement of the respiratory muscles. Treatment includes supportive care, intubation, and early administration of botulinum antitoxin.
