Botulinum toxin Botulinum toxin (BTX) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species.[1] It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction and thus causes flaccid paralysis. Infection with the bacterium causes the disease botulism.

Botulism Introduction. Botulism is a rare but potentially fatal condition caused by toxins produced by Clostridium botulinum bacteria. The toxins produced by C. botulinum are some of the most powerful toxins known to science.otulism is caused by the bacteria Clostridium botulinum, found in soil, dust and river or sea sediments.

- In addition, these toxins are a concern in bioterrorism. Last Updated: June 2010 Importance Botulism is caused by botulinum toxins, neurotoxins produced by Clostridium botulinum and a few other species of Clostridium. By binding to nerve endings, these toxins cause progressive flaccid paralysis in humans and animals.otulism Last Updated: June 2010 © 2010 page 2 of 11 Group III C. botulinum strains, which produce toxins C or D, are usually associated with botulism in animals. Group IV C. botulinum produces the type G toxin and has been reclassified as the new species Clostridium argentinense.

Botox Also called: Botulinum toxin type A. Botox is a drug made from a toxin produced by the bacterium Clostridium botulinum. It's the same toxin that causes a life-threatening type of food poisoning called botulism. Doctors use it in small doses to treat health problems, including. Temporary smoothing of facial wrinkles and improving your appearance.

Botulinum toxin Botulinum toxin (BTX) is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species. Botulinum toxin causes the disease botulism, however it is also used commercially in medicine, cosmetics, and research. There are seven types of botulinum toxin, named type A–G. Type A and B are capable of causing disease in humans, and are also used commercially and medically.

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.

BOTULINUM TOXIN Later it was found that 4 types of bacteria can produce this toxin, Clostridium botulinum, C. butyricum, C. baratii and C. argentinense, and there are 7 distinct types of the toxin known, labelled A through G, most have several subtypes also.The Clostridium botulinum bacteria responsible.he bacteria produce Botulinum Toxin (BTX) by anaerobic respiration, so it commonly occurs in canned-food containers, where there is no oxygen. When ingested, BTX causes botulism, a serious illness which begins by causing the paralysis of the face muscles and then the paralysis of most of the body.

Toxic Shock Syndrome Toxic Shock Syndrome Causes. Toxic shock syndrome is caused by toxins produced by bacteria. Only certain rare strains of specific bacteria produce these poisons. As the bacterial toxins are released into the bloodstream, they begin to overstimulate the immune system in the body. This, in turn, causes the severe symptoms of toxic shock syndrome.
