Does Ocean Sunfish Mola spp. (Tetraodontiformes: Molidae) Represent a Risk for Tetrodotoxin Poisoning in the Portuguese Coast? [PDF]

Marine Drugs, 2022
Tetrodotoxin (TTX) is a potent neurotoxin naturally occurring in terrestrial and marine organisms such as pufferfish. Due to the risk of TTX poisoning, fish of Tetraodontidae family and other puffer-related species must not be placed in the EU markets ...

Analytical Method Optimization of Tetrodotoxin and Its Contamination in Gastropods [PDF]

Foods, 2023
Tetrodotoxin (TTX) is an extremely potent marine biotoxin. An analytical method was developed for both trace contamination and extremely high levels of TTX in gastropods by liquid chromatography-tandem mass spectrometry (LC-MS/MS) with clean-up of cation

Lack of tetrodotoxin analogues and individual metabolomic profiling of the cryptic frog Colostethus imbricolus. [PDF]

PLoS ONE
Poison frogs (Dendrobatoidea) are characterized by the great diversity of alkaloids discovered in their skin. However, most of these alkaloids have been found in brightly colored species and there is a wide lack of knowledge of alkaloid profiles in the ...

Tetrodotoxin and Its Analogues in Cephalothrix cf. simula (Nemertea: Palaeonemertea) from the Sea of Japan (Peter the Great Gulf): Intrabody Distribution and Secretions [PDF]

Toxins, 2020
Some nemertean species from the genus Cephalothrix accumulate tetrodotoxin (TTX) in extremely high concentrations. The current study is the first to provide high-performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS) data on tetrodotoxin

Identification of Deoxy- and <i>epi</i>-Tetrodotoxin Analogues from the Newt <i>Cynops ensicauda popei</i> Suggests Stepwise Oxidation in Terrestrial Tetrodotoxin Biosynthesis. [PDF]

J Nat Prod
Tetrodotoxin (TTX, 1) is a potent neurotoxin that selectively blocks voltage-gated sodium channels and occurs in various marine and terrestrial organisms, yet its biosynthetic pathway remains unresolved. In this study, five deoxy-type TTX analogues were identified from the toxic newt Cynops ensicauda popei.

Keeping Lagocephalus sceleratus off the Table: Sources of Variation in the Quantity of TTX, TTX Analogues, and Risk of Tetrodotoxication [PDF]

Toxins, 2021
The invasion of the tetrodotoxin (TTX)-bearing silver-cheeked toadfish and potential poisoning due to its consumption (tetrodotoxication) threatens public safety in the Mediterranean Sea.

Cost-Effective and Rapid Detection of Tetrodotoxin Using Indium Tin Oxide Electrodes via In Vitro Electrophysiology and Electrochemistry [PDF]

Toxins
The real-time, cost-effective detection of marine toxins like tetrodotoxin (TTX) remains a significant challenge for the scientific community. Traditional methods, including cell-based assays (CBAs), high-performance liquid chromatography (HPLC), and ...

Tetrodotoxins in Tissues and Cells of Different Body Regions of Ribbon Worms Kulikovia alborostrata and K. manchenkoi from Spokoynaya Bay, Sea of Japan [PDF]

Toxins
Nemerteans, or ribbon worms, possess tetrodotoxin and its analogues (TTXs), neurotoxins of bacterial origin, which they presumably use for capturing prey and self-defense.

Tetrodotoxin: Chemistry, Toxicity, Source, Distribution and Detection

Toxins, 2014
Tetrodotoxin (TTX) is a naturally occurring toxin that has been responsible for human intoxications and fatalities. Its usual route of toxicity is via the ingestion of contaminated puffer fish which are a culinary delicacy, especially in Japan.
