AbstractBlue‐green algae are found in lakes, ponds, rivers and brackish waters throughout the world. In case of excessive growth such as bloom formation, these bacteria can produce inherent toxins in quantities causing toxicity in mammals, including humans. These cyanotoxins include cyclic peptides and alkaloids.

Epsilon toxin: a fascinating pore‐forming toxin
The FEBS Journal, 2011Epsilon toxin (ETX) is produced by strains of Clostridium perfringens classified as type B or type D. ETX belongs to the heptameric β‐pore‐forming toxins including aerolysin and Clostridium septicum alpha toxin, which are characterized by the formation of a pore through the plasma membrane of eukaryotic cells consisting in a β‐barrel of 14 amphipatic β

Clinical Reviews in Allergy, 1993
We have presented in some detail the more common clinical syndromes produced by the ingestion of natural seafood toxins, and touched on those that could be of interest to the international traveler and to the sport fisherman. For the practicing allergist, knowledge of this wide array of clinical syndromes of toxicity is of paramount importance for the ...

Detoxification of a bacterial toxin by the toxin itself
Trends in Pharmacological Sciences, 2001Abstract Several bacterial protein toxins act by forming oligomers on the cell surface. A novel approach to the prevention of the damage caused by oligomeric pore-forming toxins has recently been discovered using one such protein: the protective antigen (PA) of Bacillus anthracis .

Scientific American, 1994
On May 2, 1878, George Francis of Adelaide, Australia, published the Þrst scholarly description of the potentially lethal eÝects produced by cyanobacteriaNthe microorganisms sometimes called blue-green algae or, more colloquially, pond scum. In a letter to Nature he noted that an alga he thought to be Nodularia spumigena had so proliferated in the ...

Purpose of reviewPain is a distressing protective sensory experience warning of actual or potential tissue damage. Natural toxins have evolved to exploit pain and related neuronal pathways to facilitate prey capture and for defence, often producing either numbness, paralysis or intense pain by selectively modulating ion channels and receptors in pain ...

Toxins are produced by numerous microorganisms and invertebrates as well as by higher plants and animals. Venoms are produced by many groups of animals, from coelenterates to vertebrates. While toxins and venoms are the primary toxicological concern in natural ecosystems, they are frequently of importance in agroecosystems and in military deployments ...

Toxins and Their Phytoremediation
2010The agricultural and industrial revolutions in the last few decades have resulted in increased concentration of toxins in our environment that are now-a-days a major cause of toxicity in plants and animals. Among different toxins, increasing levels of salts, heavy metal, pesticides and other chemicals are posing a threat to agricultural as well as ...
