Distribution of paralytic toxins in California shellfish

Toxicon, 1985
Samples of Saxidomus nuttali and Mytilus californianus collected during the 1981 dinoflagellate bloom at Bodega Bay, California, were analyzed for the presence of paralytic toxins. Neck tissue of S. nuttali contained saxitoxin (STX) and neoSTX (95% of the total toxicity), whereas the bodies contained neoSTX and a mixture of the gonyautoxins.

PARALYTIC SHELLFISH TOXINS IN TROPICAL OCEANS

Toxin Reviews, 2006
The tropics possess some of the world's richest marine environments, most notably coral reefs. Concealed within these ecosystems are a group of potent neurotoxins called the paralytic shellfish toxins (PSTs), the most famous of which is saxitoxin. Thirty years ago, PSTs were recognized as a major danger to seafood consumers in the tropics. The tropical

Bacterial degradation of paralytic shellfish toxins

Toxicon, 2008
Bacteria isolated from the digestive tracts of blue mussels (Mytilus edulis) contaminated with paralytic shellfish toxins (PSTs) were screened for the ability to reduce the toxicity of a PST mixture in vitro. Bacteria were isolated on marine agar and grown in marine broth supplemented with a mussel extract and an algal extract containing PSTs ...

PARALYTIC SHELLFISH TOXINS SEEM ABSENT IN EXTRACTS OF DIARRHETIC SHELLFISH TOXINS

Environmental Toxicology and Chemistry, 1991
Abstract It has been assumed that the water-soluble paralytic shellfish toxins are extracted and concentrated by the organic-solvent extraction method used for diarrhetic shellfish toxins. As diarrhetic toxin extracts of mussels with high levels of paralytic toxins are found nontoxic, it appears that paralytic toxins are not present in ...

Paralytic shellfish toxins – Call for uniform reporting units

Toxicon, 2020
Paralytic shellfish toxins (PSTs) are a group of over 50 closely related naturally occurring tetrahydropurine toxins with saxitoxin (STX) as one of the most common and potent. Saxitoxin was first isolated and characterised from the butter clam Saxidomus giganteus as the dihydrochloride salt (Schantz et al., 1975).

Proficiency studies on the determination of paralytic shellfish poisoning toxins in shellfish

Food Additives & Contaminants, 2004
Paralytic shellfish poisoning toxins are produced by dinoflagellates. Shellfish filtering these unicellular algae will accumulate the toxins and pose a health risk when consumed by man. In the European Union, paralytic shellfish poisoning toxins in bivalve molluscs are regulated at a maximum content of 80 microg/100 g (91/492/EEC).

Fluorometric Detection of Paralytic Shellfish Poisoning Toxins

Analytical Biochemistry, 1998
A rapid qualitative screening method was developed for the fractionation of paralytic shellfish poisoning toxins. Periodic acid, t-butyl hydroperoxide, and hydrogen peroxide were tested as oxidants for the fluorometric detection of paralytic shellfish toxins.

Radioimmunoassay of paralytic shellfish toxins in clams and mussels

Bulletin of Environmental Contamination and Toxicology, 1987
Shellfish contaminated with paralytic shellfish poisons (PSP) compromise human health. The threat of this contamination results in enormous economic losses in the recreational and commercial exploitation of shellfish resources in the affected areas. Most states deal with the PSP problem either by prohibiting the collection of shellfish during certain ...

Paralytic shellfish toxins and associated toxin profiles in bivalve mollusc shellfish from Argentina

Harmful Algae, 2020
Paralytic Shellfish Poisoning is a potentially fatal syndrome, resulting from the filter-feeding activities of marine molluscs accumulating harmful neurotoxins naturally occurring in microalgae. Outbreaks are well recognised throughout most regions of the world, but with the highest levels of toxicity to date recorded in mussels from Argentina.

Laboratory bioproduction of paralytic shellfish toxins in dinoflagellates

2001
Publisher Summary It is feasible to produce milligram quantities of Paralytic shellfish toxins (PSTs) as a supply of the pure toxins for R&D and monitoring studies using the algal culture approach. PSTs are a family of marine biotoxins produced by a number of toxic dinoflagellates involved in harmful algal blooms or red tides.
