Toxins: Bacterial and Marine Toxins
Clinics in Laboratory Medicine, 2006The term toxin refers in a specific way to a toxic substance of biologic origin; that is, a true toxin is a poison produced by a living organism. The purpose of this article is to review some of the most potentially dangerous toxins of concern today. Mechanisms of action, routes of exposure, diagnostic tools, and treatment recommendations are addressed.

Oceans provide enormous and diverse space for marine life. Invertebrates are conspicuous inhabitants in certain zones such as the intertidal; many are soft-bodied, relatively immobile and lack obvious physical defenses. These animals frequently have evolved chemical defenses against predators and overgrowth by fouling organisms.

Marine neurotoxins: Ingestible toxins
Current Treatment Options in Neurology, 2004Fish and shellfish account for a significant portion of food-borne illnesses throughout the world. In general, three classes of diseases result from seafood consumption--intoxication, allergies, and infections. In this review, the authors discuss several seafood-borne toxins, including domoic acid, which acts on the central nervous system. In addition,

Marine toxins and nephrotoxicity:Mechanism of injury
Toxicon, 2019Marine toxins are known among several causes of toxin induced renal injury. Enzymatic mechanism by phospholipase A2 is responsible for acute kidney injury (AKI) in sea snake envenoming without any change in cardiac output and systemic vascular resistance.

Chemosensors for the Marine Toxin Saxitoxin
Journal of the American Chemical Society, 2002Eleven anthracylmethyl crown ethers have been synthesized and evaluated as fluorescence sensors for the marine toxin saxitoxin. Fluorescence enhancement data are consistent with a 1:1 binding complex for all crowns. The binding constants are in the range of 10(4) M(-)(1) in ammonium phosphate buffer (pH 7.1) in 80% ethanol solvent.

A Perspective on the Toxicology of Marine Toxins
Chemical Research in Toxicology, 2012Although there has been much progress with regard to marine toxins from dinoflagellates, much remains to be done. Because these compounds are a seafood consumer risk, the demands cover from legislative to scientific aspects. Legislation is required for all new toxins that appear in the coasts.

Wiener medizinische Wochenschrift (1946), 2001
The consumption of seafood, which is contaminated by toxines of red tides, is a common cause of disease in tropic regions. The most important diseases, which are caused by red tides are Paralytic Shellfish Poisoning (PSP), Diarrhetic Shellfish Poisoning (DSP), Neurotoxic Shellfish Poisoning (NSP), Amnesic Shellfish Poisoning (ASP), Ciguatera Fish ...

Marine Toxins and Nonmarine Toxins: Convergence or Symbiotic Organisms?
Journal of Natural Products, 2004Bioactive marine natural products occur only rarely in nonmarine sources. The converse also is true. Divergent evolutionary pathways for the biosynthesis of bioactive secondary metabolites seem to be the rule. Marine biosynthetic pathways lead to a wide variety of different structural classes, among which polyethers, macrolides, terpenes, unusual amino

Domoic acid: a fascinating marine toxin
Environmental Toxicology and Pharmacology, 2001There are indications that toxic algal blooms are increasing because of pollution of coastal waters and worldwide shipping. This mini-review deals with the marine biotoxin domoic acid, also known as amnesic shellfish poison, and its main producing pennate diatom genus Pseudo-nitzschia (Bacillariophyceae).
