Paralytic Shellfish Poisons of Ormer, Haliotis tuberculata, from Spain

Paralytic shellfish poisoning in Haliotis tuberculata from the

In order to clarify the origin of Paralytic Shellfish Toxins occurring in the ormers, Haliotis tuberculata, various studies were conducted to describe toxicity distribution by area, length and parts of the mollusc. Ormer toxicity from different locations of the Galician coast had a confidence interval of 252±25 μg STX eq/100 g of meat (μg of equivalents of saxitoxin/100 g) by mouse bioassay ana...

Evidence for paralytic shellfish poisons in the freshwater cyanobacterium Lyngbya wollei (Farlow ex Gomont) comb. nov.

Lyngbya wollei (Farlow ex Gomont) comb. nov., a perennial mat-forming filamentous cyanobacterium prevalent in lakes and reservoirs of the southeastern United States, was found to produce a potent, acutely lethal neurotoxin when tested in the mouse bioassay. Signs of poisoning were similar to those of paralytic shellfish poisoning. As part of the Tennessee Valley Authority master plan for Gunter...

Ichthyotoxicity of Paralytic Shellfish Poison

Attempts were made to examine the ichthyotoxicity of paralytic shellfish poison (PSP) in sixteen species of marine and freshwater fishes. Most of them showed minimum lethal doses (LD100) ranging from 1-8 MU/20g body weight when injected with a partially purified PSP intra peritoneally. Exceptionally, several fishes such as a goby Acanthogobius flavimanus (LD100, 9-17 MU/20g) and puffer Fugu nip...

Paralytic Shellfish Poisoning Toxins: Biochemistry and Origin

Plankton feeders such as bivalves often become toxic. Human consumption of the toxic bivalve causes severe food poisoning, including paralytic shellfish poisoning (PSP) which is the most dangerous because of the acuteness of the symptoms, high fatality and wide distribution throughout the world. Accumulation of PSP toxins in shellfish has posed serious problems to public health and fisheries in...
