Botulism causes
High-Yield Explanation
Clostridium botulinum produces Type A toxin. It acts by blocking the production or release of acetylcholine at the synapses and neuromuscular junction. Thus block neuromuscular transmission. Onset is marked by diplopia, dysphagia, and dysahria due to cranial nerve involvement. Symmetric descending flaccid paralysis is a characteristic pattern, ending in death by respiratory paralysis.
