- 1 A toxin is a highly toxic protein produced by certain plants, animals or pathogenic bacteria. 2  Examples include snake venom and anthrax. 3  All toxins are toxicants, but only those toxicants produced by living organisms are toxins. 4  Substances that are toxic only to specific types of cells or organs are called cytotoxins.

endotoxin endotoxin. a heat-stable toxin associated with the outer membranes of certain gram-negative bacteria, including Brucella, Neisseria, and Vibrio species. Endotoxins are not secreted but are released only when the cells are disrupted; they are less potent and less specific than the exotoxins; and they do not form toxoids. toxin that forms an integral part of the cell wall of certain bacteria and is only released upon destruction of the bacterial cell. Endotoxins are less potent and less specific than most exotoxins and do not form toxoids. Also called intracellular toxin. en′do·tox′ic adj.

Exotoxin An exotoxin is a toxin secreted by bacteria. An exotoxin can cause damage to the host by destroying cells or disrupting normal cellular metabolism.They are highly potent and can cause major damage to the host. Exotoxins may be secreted, or, similar to endotoxins, may be released during lysis of the cell.n exotoxin is a toxin secreted by bacteria.

What Is Holistic Medicine? Holistic medicine is also based on the belief that unconditional love and support is the most powerful healer and a person is ultimately responsible for his or her own health and well-being. Other principles of holistic medicine include the following: 1  All people have innate healing powers.2  The patient is a person, not a disease. 3  Healing takes a team approach involving the patient and doctor, and addresses all aspects of a person's life using a variety of health care practices.

- Knowledge center. Botox is a drug made from a neurotoxin produced by the bacterium Clostridium botulinum called botulinum toxin. It is used medically to treat certain muscular conditions and cosmetically remove wrinkles by temporarily paralyzing muscles. Botox is the most popular cosmetic surgery treatment, with more than 6 million Botox treatments administered each year. 2  Botox is a neurotoxin derived from Clostridium botulinum, an organism found in the natural environment where it is largely inactive and non-toxic.

Neurotoxin Tetraethylammonium (TEA) is a compound that, like a number of neurotoxins, was first identified through its damaging effects to the nervous system and shown to have the capacity of inhibiting the function of motor nerves and thus the contraction of the musculature in a manner similar to that of curare.

toxin tox·in. A poisonous substance produced by a living organism. Toxins can be products of ordinary metabolism (such as lactic acid), can be produced to kill or immobilize prey (such as the toxins in snake venom), or can be produced for self-defense (such as the cyanide produced by several plants).oxin. n. 1. (Pathology) any of various poisonous substances produced by microorganisms that stimulate the production of neutralizing substances (antitoxins) in the body. See also endotoxin, exotoxin. 2. (Biology) any other poisonous substance of plant or animal origin.

Botulism Neurotoxin, synthesized and secreted by Clostridium botulinum bacteria (and a few other Clostridium species), cause botulism. The toxin causes the disease by blocking the release of acetylcholine from motor nerve endings.This result produces the symptoms associated with botulism.ood-borne botulism can be especially dangerous because many people can be poisoned by eating even small amounts of neurotoxin-contaminated food. A botulism outbreak is a public-health emergency that is reportable to the U.S. government.

Exotoxins and Endotoxins and Difference between Exotoxins and Endotoxins 5 / 5  ( 3 ) Exotoxins may travel from a focus of infection to distant part of the body and cause damage. E.g. Neurotoxin (botulinum toxin, tetanus toxin), Enterotoxin (cholera toxin), Cytotoxin. Endotoxins: Definition: Endotoxins are lipopolysaccharides toxin produced by Gram Negative bacteria.The name endotoxin is derived from the fact that these toxins are generally cell bound and released only when the cell lyses. Basic properties and differences between Exotoxins and Endotoxins.xotoxins may travel from a focus of infection to distant part of the body and cause damage. E.g. Neurotoxin (botulinum toxin, tetanus toxin), Enterotoxin (cholera toxin), Cytotoxin. Endotoxins: Definition: Endotoxins are lipopolysaccharides toxin produced by Gram Negative bacteria.

toxin poison produced by living organisms. Toxins are classified as either exotoxins or endotoxins. Exotoxins are a diverse group of soluble proteins released into the surrounding tissue by living bacterial cells. Exotoxins have specific reaction sites in the host; e.g., tetanus and botulinum exotoxins affect nerve tissue, and streptococcal toxins attack vascular tissue. Plants and animals also produce protein toxins.
