Presence of tetrodotoxin and tetrodotoxin-producing bacteria in freshwater sediments.
The occurrence of tetrodotoxin (TTX) in sediment from Lake Suwa, Japan, was confirmed by a tissue culture assay, high-performance liquid chromatography, and gas chromatography-mass spectrometry. Altogether, 17 TTX-producing bacteria belonging to five genera were isolated from Lake Suwa and Pond Inokasira. Our results indicate that TTX and TTX-producing bacteria occur even in freshwater environm...
متن کاملNo ability to produce tetrodotoxin in bacteria.
Bacterial production of tetrodotoxin (TTX) was first reported by Yasumoto et al. (8). Detection of bacterially produced TTX has been primarily by high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS). In September 1995, Applied and Environmental Microbiology published a paper indicating that both the HPLC and GC-MS methods lacked specificity for TTX (3)....
متن کاملTetrodotoxin-Producing Bacteria: Detection, Distribution and Migration of the Toxin in Aquatic Systems
This review is devoted to the marine bacterial producers of tetrodotoxin (TTX), a potent non-protein neuroparalytic toxin. In addition to the issues of the ecology and distribution of TTX-producing bacteria, this review examines issues relating to toxin migration from bacteria to TTX-bearing animals. It is shown that the mechanism of TTX extraction from toxin-producing bacteria to the environme...

In this Quick Guide, Lorentz et al. discuss the function of tetrodotoxin and its distribution in the animal kingdom.
متن کاملCable Bacteria in Freshwater Sediments
In marine sediments cathodic oxygen reduction at the sediment surface can be coupled to anodic sulfide oxidation in deeper anoxic layers through electrical currents mediated by filamentous, multicellular bacteria of the Desulfobulbaceae family, the so-called cable bacteria. Until now, cable bacteria have only been reported from marine environments. In this study, we demonstrate that cable bacte...
