Journal ArticleDOI
Brevetoxicosis: red tides and marine mammal mortalities.
Leanne J. Flewelling,Jerome Naar,Jay P. Abbott,Daniel G. Baden,Nélio B. Barros,Gregory D. Bossart,Marie-Yasmine Dechraoui Bottein,Daniel G. Hammond,Elsa M. Haubold,Cynthia A. Heil,Michael S.

TL;DR: It is shown that fish and seagrass can accumulate high concentrations of brevetoxins and that these have acted as toxin vectors during recent deaths of dolphins and manatees, respectively, and a new vector mechanism for brevetoxin spread through food webs that poses a threat to upper trophic levels is revealed.
Journal ArticleDOI
Karenia brevis red tides, brevetoxins in the food web, and impacts on natural resources: decadal advancements.
TL;DR: Unexplained fish kills and other animal mortalities in areas where red tide is endemic are being increasingly linked with post-bloom exposures of biota to brevetoxins.
Journal ArticleDOI
A competitive ELISA to detect brevetoxins from Karenia brevis (formerly Gymnodinium breve) in seawater, shellfish, and mammalian body fluid
Jerome Naar,Andrea J. Bourdelais,Carmelo R. Tomas,Julia Kubanek,Philip L Whitney,Leanne J. Flewelling,Karen Steidinger,Johnny Lancaster,Daniel G. Baden +8 more
TL;DR: A competitive enzyme-linked immunosorbent assay (ELISA) to analyze brevetoxins, using goat anti-brevetoxin antibodies obtained after immunization with keyhole limpet hemocyanin-Brevetoxin conjugates, in combination with a three-step signal amplification process is developed.
Journal ArticleDOI
Saxitoxin puffer fish poisoning in the United States, with the first report of Pyrodinium bahamense as the putative toxin source.

TL;DR: Puffer fish are confirmed to be a hazardous reservoir of STXs in Florida’s marine waters and implicate the dinoflagellate P. bahamense as the putative toxin source.
Journal ArticleDOI
Brevetoxins, like ciguatoxins, are potent ichthyotoxic neurotoxins that accumulate in fish.

TL;DR: It is observed that levels of brevetoxins in the muscle of fish at all trophic levels rise significantly, but not to dangerous levels, during a K. brevis bloom, and levels were highest in fish liver and stomach contents, and increased during and immediately following the bloom.
