The difference in paralytic shellfish poisoning (PSP) toxin accumulation in the crabs Telmessus acutidens and Charybdis japonica was investigated at Onahama, Fukushima Prefecture, from 2002 to 2005. The level of toxin accumulation in the hepatopancreas of T. acutidens corresponded to that of mussels when examined on a yearly basis. In 2003, some crabs had a high toxicity of approximately 1000 MU, which compares to one-third of the human minimum lethal dose. Therefore T. acutidens should be…

Accumulation of paralytic shellfish poisoning toxin by the swimming crab Charybdis japonica in Kure Bay, Hiroshima Prefecture

The toxin profiles, shown in the feeding experiments, suggest that the transformation of PSP toxin occurs in the crab because dcGTX2 anddcGTX3 was detected in all crab specimens despite the lack of these analogs in the mussels used as feed.

Prevalence, Variability and Bioconcentration of Saxitoxin-Group in Different Marine Species Present in the Food Chain

The identification in multiple vectors, as well as in unregulated species, suggests that a risk assessment and risk management update are required; also, chemical and specific analyses for the detection of all analogues associated with the STX-group need to be established.

Presence of Alexandrium catenella and paralytic shellfish toxins in finfish, shellfish and rock crabs in Monterey Bay, California, USA

The presence of PSTs in several of these organisms reveals that toxins produced by A. catenella are more prevalent in California food webs than previously thought and also indicates potential routes of toxin transfer to higher trophic levels.

Development of Ultra-Performance Liquid Chromatography with Post-Column Fluorescent Derivatization for the Rapid Detection of Saxitoxin Analogues and Analysis of Bivalve Monitoring Samples

A rapid detection method for the analysis of STXs using ultra-performance liquid chromatography with post-column fluorescent detection is described and water depths and sampling points optimal for shellfish toxin monitoring are investigated.

Marine Toxins Detection by Biosensors Based on Aptamers

The detection of marine toxins by aptamer-based biosensors, as well as the selection approach for the systematic evolution of ligands by exponential enrichment (SELEX), the aptamer sequences are reviewed.

Eco Toxins and Their Impacts on Human Health

Every organism depends on the environment. But day by day the pollution increases due to various causative factors which release a number of toxins. These toxins damage the whole ecosystem and impact

The mussel Mytilus edulis and the cultured ark shell Anadara broughtonii in the southeast coasts of the Seto Inland Sea were contaminated with paralytic shellfish poison (PSP), and bivalves collected during the toxification period were dissected into five tissues, mantle, adductor muscle, hepatopancreas, gills and "others", and submitted to high-performance liquid chromatography (HPLC).

During the summer of 2002 there were several episodes of human intoxication after consumption of brown crabs caught along the Norwegian south coast, where one of the well-known phycotoxins, the diarrhoetic shellfish poisoning (DSP) complex, routinely found in blue mussels was found.

Paralytic Shellfish Poisoning Toxins: Biochemistry and Origin

The present study revealed that organisms bearing either TTX or PSP toxins possess both toxins, although the proportion of both is different among the specimens, strongly suggest that a similar mechanism between bacteria and toxic organisms is involved in the production of TTX and/or PSP toxins in toxic organisms.
