Guidance Level for Brevetoxins in French Shellfish [PDF]
Marine Drugs, 2021 Brevetoxins (BTXs) are marine biotoxins responsible for neurotoxic shellfish poisoning (NSP) after ingestion of contaminated shellfish. NSP is characterized by neurological, gastrointestinal and/or cardiovascular symptoms. The main known producer of BTXs

When the Red Tide Rolls In: A Red Tide Associated Angioedema Case Report [PDF]
Clinical Practice and Cases in Emergency Medicine, 2021 Introduction: Histamine-mediated angioedema is a potentially life-threatening reaction following exposures that incite mast cell activation. In Florida, red tides are a frequent phenomenon caused by overgrowth of the harmful algae species Karenia brevis,

Use of intravenous lipid emulsion therapy as a novel treatment for brevetoxicosis in sea turtles [PDF]
Scientific Reports, 2021 The southwest coast of Florida experiences annual red tides, a type of harmful algal bloom that results from high concentrations of Karenia brevis. These dinoflagellates release lipophilic neurotoxins, known as brevetoxins, that bind to sodium channels ...
