The First Data on the Complete Genome of a Tetrodotoxin-Producing Bacterium
Toxins, 2021 Tetrodotoxin (TTX)-producing bacteria have attracted great interest as a model system for study of the TTX biosynthetic route. Here, we report the complete genome of the TTX-producing bacterium Bacillus sp. 1839.

A Review on Climate Change Redefining Tetrodotoxin Accumulation and Ecological Dynamics in Pufferfishes [PDF]
Marine DrugsPufferfishes (Tetraodontidae) accumulate tetrodotoxin, a potent neurotoxin, primarily through microbial and trophic pathways rather than endogenous biosynthesis, linking their toxicity directly to marine microbial ecology and food-web structure ...

Gut Epithelium of the Highly Toxic Ribbon Worm Cephalothrix cf. simula (Palaeonemertea, Nemertea) Contains Tetrodotoxin-Positive Bacterial Endosymbionts [PDF]
ToxinsTetrodotoxin (TTX), widely known as pufferfish venom, is a low-molecular-weight guanidinium neurotoxin. It can accumulate to extremely high concentrations in certain animals, including pufferfish, blue-ringed octopuses, flatworms, and nemerteans. However,

Tetrodotoxin Profiles in Xanthid Crab Atergatis floridus and Blue-Lined Octopus Hapalochlaena cf. fasciata from the Same Site in Nagasaki, Japan [PDF]
Toxins, 2023 The xanhid crab Atergatis floridus and the blue-lined octopus Hapalochlaena cf. fasciata have long been known as TTX-bearing organisms. It has been speculated that the TTX possessed by both organisms is exogenously toxic through the food chain, since ...

The Chemical and Evolutionary Ecology of Tetrodotoxin (TTX) Toxicity in Terrestrial Vertebrates
Marine Drugs, 2010 Tetrodotoxin (TTX) is widely distributed in marine taxa, however in terrestrial taxa it is limited to a single class of vertebrates (Amphibia). Tetrodotoxin present in the skin and eggs of TTX-bearing amphibians primarily serves as an antipredator ...

Marine Drugs, 2011 Puffer fish, Takifugu niphobles, collected from the Hong Kong coastal waters were screened for tetrodotoxin-producing bacteria. A Gram-negative, non-acid-fast, non-sporing and rod shaped bacterial strain (designated as gutB01) was isolated from the ...

From Poison to Promise: The Evolution of Tetrodotoxin and Its Potential as a Therapeutic
Toxins, 2021 Tetrodotoxin (TTX) is a potent neurotoxin that was first identified in pufferfish but has since been isolated from an array of taxa that host TTX-producing bacteria.
