Toxicon, 2021
Brevetoxins were confirmed in urine specimens from patients diagnosed with neurotoxic shellfish poisoning (NSP) after consumption of gastropods that were recreationally harvested from an area previously affected by a Karenia brevis bloom. Several species of gastropods (Triplofusus giganteus, Sinistrofulgur sinistrum, Cinctura hunteria, Strombus alatus,

Biomarkers of Neurotoxic Shellfish Poisoning
Toxicon, 2008Urine specimens from patients diagnosed with neurotoxic shellfish poisoning (NSP) were examined for biomarkers of brevetoxin intoxication. Brevetoxins were concentrated from urine by using solid-phase extraction (SPE), and analyzed by enzyme-linked immunosorbent assay (ELISA) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Urine extracts

Harmful Algae, 2015
Abstract Neurotoxic shellfish poisoning (NSP) is caused by the consumption of molluscan shellfish meat contaminated with brevetoxins produced by the dinoflagellate, Karenia brevis (K. brevis). During a prolonged and intermittent K. brevis bloom starting in 2005 lasting through early 2007 in the Gulf of Mexico off southwest Florida coast, there were ...

Natural Toxins, 1999
A new brevetoxin B analog, brevetoxin B4 (BTXB4), was isolated as the major toxin in greenshell mussels, Perna canaliculus, collected in New Zealand at the time of the neurotoxic shellfish poisoning incident. The new analog accounted for nearly two-thirds of the mouse lethality of the shellfish and was determined to be a mixture of N-myristoyl-BTXB2 ...

Brevetoxin B1 (BTX-B1) was isolated from Austrovenus stutchburyi following the 1992-1993 outbreak of neurotoxic shellfish poisoning (NSP) in New Zealand. We report here the first isolation of PbTx-3 from the same shellfish and the development of a procedure for quantitative determination of PbTx-3 and BTX-B1.

Toxicon, 2004
We examined metabolism of PbTxs in New Zealand cockle, Austrovenus (A.) stutchburyi, and greenshell mussel, Perna (P.) canaliculus, by means of liquid chromatography coupled with tandem mass spectrometry. PbTx-2, PbTx-3 and BTX-B5 were detected in Karenia (K.) brevis culture medium in the ratio of ca. 50:2:5.

Previously, we found brevetoxins PbTx-3, BTX-B5 and BTX-B1 in cockle, Austrovenus (A.) stutchburyi, PbTx-2, PbTx-3 and BTX-B1 in Pacific oyster, Crassostrea (C.) gigas and PbTx-3 and BTX-B1 in greenshell mussel, Perna (P.) canaliculus following outbreak of neurotoxic shellfish poisoning (NSP) in New Zealand by isolation and/or liquid chromatography ...

Neuroexcitatory and neurotoxic actions of the amnesic shellfish poison, domoic acid
NeuroReport, 1994We have investigated the action of domoic acid in the mouse brain following systemic exposure. Domoic acid increased c-fos mRNA within 15 min and its translational product (c-Fos) within 1 h. c-Fos immunoreactivity was most prominent in the hippocampal formation, lateral septal nucleus, olfactory bulb, area postrema and the nucleus of the solitary ...
