Comparison of during-bloom and inter-bloom brevetoxin and saxitoxin concentrations in Indian River Lagoon bottlenose dolphins, 2002-2011.

Aquatic Toxicology, 2019
Harmful algal bloom (HAB) toxins have severe negative impacts on marine mammals, particularly for Florida bottlenose dolphins (Tursiops truncatus) which frequently experience mass mortality events.

Distribution and elimination of brevetoxin PbTx-3 in rats

Toxicon, 1990
After i.v. administration, [3H]PbTx-3 was rapidly cleared from the blood; less than 10% remained after 1 min. Within 30 min, radiolabel distributed to skeletal muscle (69.5%), liver (18.0%), and intestinal tract (8.0%). Over 24 hr, radiolabel decreased in muscle, remained constant in liver, and increased in the intestinal tract and feces.

Changes in the neurotransmitter profile in the central nervous system of marine medaka (Oryzias melastigma) after exposure to brevetoxin PbTx-1 - A multivariate approach to establish exposure biomarkers.

Science of the Total Environment, 2019
A strategy to construct multivariate biomarkers for exposure to algal neurotoxins via correlating changes to the profiles of a series of neurotransmitters and their metabolites in the central nervous system (CNS) of exposed test organism is reported.

Brevetoxin binding: molecular pharmacology versus immunoassay

Toxicon, 1988
Brevetoxin PbTx-3 isolated from Florida's red tide dinoflagellate Ptychodiscus brevis has been produced recently in tritiated form by reductive tritiation of brevetoxin PbTx-2. Tritiated PbTx-3 has been used as a specific probe in competitive radioimmunoassays developed to detect brevetoxins in food sources, and this probe has also been utilized to ...

Brevetoxins

Brevetoxins (BTXs) are potent marine toxins produced by certain microalgae during harmful algal blooms (HABs). These lipophilic polyether compounds, notably PbTx-1 and PbTx-2, primarily affect seafood safety by bioaccumulating in filter-feeding shellfish and finfish.

Isolation and structure of a new brevetoxin analog, brevetoxin B2, from greenshell mussels from New Zealand

Tetrahedron, 1998
Abstract A new brevetoxin analog, brevetoxin B2 (BTXB2), was isolated from greenshell mussels, Perna canaliculus, collected at the time of the neurotoxic shellfish poisoning incident in New Zealand. The structure was elucidated based on NMR, CAD FAB MS/MS, and chemical degradation experiments.

Brevetoxin and saxitoxin alter shoaling dynamics in mummichog, Fundulus heteroclitus

Journal of Experimental Marine Biology and Ecology, 2019
Shoaling and social behaviors of Fundulus heteroclitus (mummichog, an estuarine killifish) were observed in response to harmful algal bloom (HAB) neurotoxin exposures.

[Ciguatoxins and brevetoxins: dissection of the neurobiological actions].

Journal de la Societe de biologie, 1999
This review focuses on the neurobiological actions of ciguatoxins and brevetoxins which are phycotoxins produced respectively by the dinoflagellates Gambierdiscus toxicus and Ptychodiscus brevis. These actions are illustrated in particular by the effects of the toxins on myelinated nerve fibres and on skeletal neuromuscular junctions of vertebrates ...
