Paralytic shellfish poisoning and palytoxin poisoning in dogs

Veterinary Record, 2020
Background Fatal cases of exposure to paralytic shellfish toxins and palytoxins have occurred in companion animals but are poorly described. Methods We describe one case of paralytic shellfish poisoning (PSP) and three cases of ...

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).

Paralytic Shellfish Poisoning: A Review

Journal of the American Veterinary Medical Association, 1977
SUMMARY Paralytic shellfish poisoning (psp) in man results from the consumption of mussels, clams, and oysters that have fed on toxic dinoflagellates. Motile, marine protozoa of the dinoflagellate group often produce “blooms,” i.e., red tides, which color the sea. Not all genera or species are toxic to fish and mammals, nor are the toxic principles the

Lethal Paralytic Shellfish Poisoning in Guatemala

The American Journal of Tropical Medicine and Hygiene, 1990
An outbreak of paralytic shellfish poisoning occurred in Champerico, on the Pacific coast of Guatemala, July-August 1987. Of 187 people affected with characteristic neurologic symptoms, 26 died. A case study implicated a species of clam, Amphichaena kindermani, harvested from local beaches as the vehicle of the neurotoxins (saxitoxins).

Paralytic shellfish poisoning in Southern China

Toxicon, 1996
The rapidly expanding mariculture and commercial region along the southern coast of China has experienced sporadic outbreaks of paralytic shellfish poisoning for nearly 30 years, yet virtually nothing is known of the nature of that toxicity or of the causative organisms.

Toxicologic studies on paralytic shellfish poison

Toxicology and Applied Pharmacology, 1960
Abstract The acute LD50's for a highly purified preparation of paralytic shellfish poison in mice were determined for the oral (263 μg/kg), intraperitoneal (10.0 μg/kg), and intravenous (3.4 μg/kg) routes. Female mice were more susceptible than males to lethal doses of the poison. Increases of pH of the injection medium or the addition of sodium ions

Paralytic Shellfish Poisons

1984
Paralytic shellfish poisons (PSP) are the toxins responsible for acute and often fatal poisonings caused by the consumption of certain shellfish. The phenomenon has been known since prehistoric times. A thorough docuinen tation of the incidents can be found in HALSTEAD’S treatise on poisonousmarine organisms (7).

Paralytic shellfish poisoning

Neurology, 1990
We report serial electrophysiologic observations in a patient with acute bulbar and respiratory paralysis following ingestion of saxitoxin-contaminated clams. Prolonged distal motor and sensory latencies, slowed conduction velocities, and moderately diminished amplitudes were present at the outset. All values returned to normal over 5 days.

Paralytic shellfish poisoning: clinical and electrophysiological observations

Journal of Neurology, 1998
In paralytic shellfish poisoning a mollusc contaminated with a toxin (saxitoxin) causes a potentially lethal disease, clinically characterised by gastrointestinal and neurological symptoms, of which possible respiratory depression is the most serious. The toxin acts by blocking the sodium channels. We report 9 Portuguese patients with this disease. The
