Tetrodotoxin (TTX) is a toxin (neurotoxic) isolated for the first time in 1909 and present in some species of fish, tetraodons.
It is also called Fugu poison, and tetraodon poison.
Tetrodotoxin is a potent neurotoxin produced by four different strains of bacteria: Aliivibrio fischeri, Pseudomonas sp, Vibrio altermonas and Vibrio alginolyticus.
Tetrodotoxin selectively blocks the pore of voltage-gated sodium channels, thus preventing the passage of nerve impulses. This blockage under a certain level is reversible.
The clinical picture is as follows:
* Impairment of the nervous system with oral and perioral paresthesia, nausea often accompanied by vomiting, sometimes with diarrhea and abdominal pain;
* Dizziness, pallor, feeling unwell, then ataxia and general numbness with the sensation of floating. * Tingling and tingling of the extremities preceding paralysis of the lower limbs and extremities;
* Changes in deep sensitivity, throat and larynx are affected very early causing dysphagia or complete aphagia, and dysphonia;
* Dilation of the pupils (mydriasis);
in the case of acute intoxication, bradycardia and hypotension, hypersalivation, hypothermia, hypersudation, asthenia;
* Cyanosis of the extremities and the lips, petechial haemorrhages on the body.
