Domoic acid (DA) is a kainic acid-type neurotoxin that causes amnesic shellfish ... New research has found that domoic acid is a heat-resistant and very stable toxin ...
Amnesic shellfish poisoning (ASP) is an illness caused by consumption of shellfish that contain the marine biotoxin called domoic acid. [1] In mammals, including humans, domoic acid acts as a neurotoxin, causing permanent short-term memory loss, brain damage, and death in severe cases.
Pseudo-nitzschia is a marine planktonic diatom genus that accounts for 4.4% of pennate diatoms found worldwide. [1] Some species are capable of producing the neurotoxin domoic acid (DA), which is responsible for the neurological disorder in humans known as amnesic shellfish poisoning (ASP). Currently, 58 species are known, 28 of which have been ...
Those found alive on the shore are ending up in the care of vets like Lauren Palmer. ... Hundreds are poisoned with something called domoic acid, a neurotoxin from a particular kind of algae in ...
Unprecedented deaths of sea lions along California's Central Coast
Some shellfish like oysters can accumulate domoic acid, a toxin produced by diatoms, which the shellfish eat. Domoic acid overstimulates glutamate receptors in the brain, which can cause anything ...
Pseudo-nitzschia australis is a pennate diatom found in temperate and sub-tropic marine waters, such as off the coast of California and Argentina. This diatom is a Harmful Micro Algae [1] that produces toxic effects on a variety of organisms through its production of domoic acid, a neurotoxin.
Nitzschia is found mostly in colder waters, and is associated with both Arctic and Antarctic polar sea ice, where it is often found to be the dominant diatom. Nitzschia includes several species of diatoms known to produce the neurotoxin known as domoic acid, a toxin responsible for the human illness called amnesic shellfish poisoning.
