These blooms can produce domoic acid
, a poison that is toxic for humans, marine mammals and seabirds when ingested."
When Pseudo-nitzschia bloom, they sometimes produce a neurotoxin called domoic acid
. Shellfish eat the algae and accumulate the toxin in their tissues, and when humans and marine mammals eat the shellfish, they can get sick, and in some cases, die.
In various parts of the world, these species have presented Domoic Acid
(DA), a neurotoxin associated with ASP.
Species that are potential producers of domoic acid
(DA) of the genus Pseudo-nitzschia are frequent components of phytoplankton in these gulfs.
The Oregon Department of Agriculture and the Oregon Department of Fish and Wildlife announce the immediate closure of recreational and commercial crabbing from the north jetty of the Coquille River, which includes the bay in Bandon, to the California border due to elevated levels of domoic acid
Excreted by a diatom known as Pseudo-nitzschia, domoic acid
is a potent neurotoxin that is taken up by algae-eating fish such as anchovies and sardines.
He describes clamming areas in Washington, the ecology and anatomy of the razor clam, the era of the NIX bacteria and domoic acid
in the clams, clamming methods, the use of clam guns, culinary aspects, and practical aspects like cleaning and keeping clams and the effects of climate change.
was an unknown algal toxin until it killed people who ate mussels harvested at Prince Edward Island in 1987," says Michelle Wood, professor of biology and scientist in the UO Institute of Ecology and Evolution.
For example, the binding of domoic acid
to the glutamate receptor can result in a series of events that result in seizures and memory loss (Bal-Price et al., 2015b; Leist et al., 2014; Watanabe et al., 2011).
is a highly potent marine toxin which is produced by Pseudo-nitzschia.
Blooms of Pseudonitzschia produce a potent neurotoxin, domoic acid
, which can accumulate in shellfish, other invertebrates, and sometimes fish, leading to illness and death in a variety of seabirds and marine mammals.
