Botulism centers on a toxin that directly disrupts nerve signaling at the neuromuscular junction. The botulinum toxin prevents acetylcholine from being released from nerve endings, so muscles can’t receive the signal to contract. This produces a distinctive pattern of weakness that is usually symmetric and descending, starting with cranial nerves (such as trouble with vision, swallowing, and speaking) and then progressing to the limbs. Fever is not a typical feature of botulism, and it is a very dangerous toxin for humans, requiring urgent medical attention. The key point is the toxin’s action: blocking acetylcholine release at the neuromuscular junction.
