Frontiers in Marine Science, 2018 In January 2015, a harmful algae bloom (HAB) of the dinoflagellate Gymnodinium catenatum occurred in the Northern Gulf of California (NGC). This species produces paralytic shellfish toxins (PSTs), a group of potent neurotoxins.

Removal of Paralytic Shellfish Toxins by Probiotic Lactic Acid Bacteria
Toxins, 2014 Paralytic shellfish toxins (PSTs) are non-protein neurotoxins produced by saltwater dinoflagellates and freshwater cyanobacteria. The ability of Lactobacillus rhamnosus strains GG and LC-705 (in viable and non-viable forms) to remove PSTs (saxitoxin (STX)

Isolation and Structure Elucidation of New and Unusual Saxitoxin Analogues from Mussels
, 2004 Three new paralytic shellfish poisoning (PSP) toxins were isolated from toxic mussels and deduced to be 11b-hydroxy-N-sulfocarbamoyl saxitoxin (M1b), 11,11-dihydroxy-N-sulfocarbamoyl saxitoxin (M3) and 11,11 dihydroxy-saxitoxin (M4) based on liquid ...

Detection of saxitoxin-producing cyanobacteria in subtropical Brazilian drinking water supply reservoir by quantitative PCR [PDF]
, 2019 Toxic cyanobacteria in public water supply reservoirs represent a serious health risk since they can release potent cyanotoxins into the water. Among the cyanotoxins are saxitoxin (SXT) and its homologs that form a group of potent neurotoxins called ...

Extraction and determination of PSP (saxitoxin and derivatives) from scallop [PDF]
, 2007 Paralytic Shellfish Poison (saxitoxin and derivatives) was extracted by HCL method from frozen scallops. The samples were collected from coastal areas of Iwate prefecture- Japan. Toxicity of the samples was determined with mouse bioassay method.

Sub-chronic feeding study of saxitoxin using mice
, 2021 Regulatory limits for shellfish toxins are often set using the results of acute toxicity testing (one-off dose) whereas in reality, people who eat shellfish often do so regularly. It is therefore important to determine the effect of shellfish toxins over

, 2009 Saxitoxin is a secondary metabolite produced by several species of dinoflagellates and cyanobacteria. The molecular target in mammals and higher eukaryotes is the sodium channel protein in nerve and muscle cells, where it binds with high affinity and ...
