Paralytic shellfish poisoning (PSP) is one of the four recognized syndromes of shellfish poisoning, which share some common features and are primarily associated with bivalve mollusks (such as mussels, clams, oysters and scallops).
Paralytic shellfish poisoning, or PSP, is caused by saxitoxin, a naturally occurring toxin that’s produced by algae. Saxitoxin is a neurotoxin, meaning it can damage nerve tissue.
What is paralytic shellfish poisoning? Paralytic shellfish poisoning, or PSP, is caused by saxitoxin, a naturally occurring toxin that’s produced by algae. Saxitoxin is a neurotoxin, meaning it can damage nerve tissue. People who eat shellfish contaminated with high levels of saxitoxins usually start feeling ill within 30 to 60 minutes ...
Saxitoxin (STX) is a potent neurotoxin and the best-known paralytic shellfish toxin. Ingestion of saxitoxin by humans, usually by consumption of shellfish contaminated by toxic algal blooms, is responsible for the illness known as paralytic shellfish poisoning (PSP).
Paralytic shellfish poisoning, or PSP, happens after consuming shellfish contaminated with saxitoxin, which can cause gastrointestinal distress, neurological symptoms, and a sensation of ...
Shellfish poisoning includes four syndromes that share some common features and are primarily associated with bivalve molluscs (such as mussels, clams, oysters and scallops.) [1] As filter feeders, these shellfish may accumulate toxins produced by microscopic organisms, such as cyanobacteria, diatoms and dinoflagellates.
PSP is the most common and severe form of shellfish poisoning and is caused by neurotoxins, called saxitoxins or paralytic shellfish toxins, that are naturally produced by marine algae, called ...
Neosaxitoxin (NSTX) is included, as other saxitoxin-analogs, in a broad group of natural neurotoxic alkaloids, commonly known as the paralytic shellfish toxins (PSTs).The parent compound of PSTs, saxitoxin (STX), is a tricyclic perhydropurine alkaloid, which can be substituted at various positions, leading to more than 30 naturally occurring STX analogues.
