Tetrodotoxin And The Threat Of Bioterrorism Biology Essay According to the New York Times, first isolated from the puffer fish, tetrodotoxin is among the most potent toxins known. It is 100 times as toxic by weight as potassium cyanide - two milligrams can kill an adult human - and it is not destroyed by cooking. Tetrodotoxin is found in more than just marine creatures.

Alexandrium catenella Alexandrium catenella is a dinoflagellate. It is among the group of Alexandrium species that produce toxins that cause paralytic shellfish poisoning, and is a cause of red tide.These organisms have been found in the west coast of North America, Japan, Australia, and parts of South Africa.he dinoflagellate produces saxitoxin, which is a highly potent neurotoxin. If consumed, this toxin can cause paralytic shellfish poisoning (PSP). By ingesting saxitoxin, humans can suffer from numbness, ataxia, incoherence, and in extreme cases respiratory paralysis and death.

Mechanism of tetrodotoxin block and resistance in sodium channels 1. Tetrodotoxin (TTX) is a guanidinium compound produced by bacteria in puffer fish and certain other animals such as octopus and chaetognatha. Due to its potent inhibitory effect on several isoforms of voltage-gated Na + (Na V) channels, TTX has been extensively studied in biological and chemical sciences [1] .1B) in TTX block of Na V channels [5] and [8] . Thus, the guanidine group of TTX may interact with the outer charged ring more intimately, rather than protruding into the filter. Here the inhibition of Na V Ab and Na V 1.4 by TTX is examined in atomic detail using molecular dynamics (MD) simulations.

- 1 EFFECTS OF SHORT-TERM (LESS THAN 8-HOURS) EXPOSURE: Tetrodotoxin interferes with the transmission of signals from nerves to muscles by blocking sodium channels. 2  This results in rapid weakening and paralysis of muscles, including those of the respiratory tract, which can lead to respiratory arrest and death.
