Pufferfish Poisoning
- Some puffer fish carry tetrodotoxin (TTX) which is one of the most potent neurotoxins known in nature.
- Tetrodotoxin blocks nerve sodium channels and can cause paralysis, respiratory failure and death.
- TTX consists of an oxygenated 2,4-dioxaadamantane core and a guanidinium group.
- TTX is heat-stable, water-soluble, and a non-protein quinazoline derivative.
- Evidence suggests that pufferfish do not synthesise the toxin themselves.
- Instead, TTX is believed to originate from symbiotic or ingested bacteria such as Vibrio, Pseudomonas, Aeromonas and Bacillus.
