- (Redirected from Bacterial toxin). Microbial toxins are toxins produced by micro-organisms, including bacteria and fungi. Microbial toxins promote infection and disease by directly damaging host tissues and by disabling the immune system.Some bacterial toxins, such as Botulinum neurotoxins, are the most potent natural toxins known.However, microbial toxins also have important uses in medical science and research.icrobial toxins promote infection and disease by directly damaging host tissues and by disabling the immune system.

Microbiology The Production of Toxins. Poisonous substances produced by microorganisms are called toxins; toxemia refers to the presence of toxins in the blood. The ability to produce toxins is called toxigenicity. Exotoxins are produced by bacteria (mostly gram-positive) and released into the surrounding medium. Exotoxins, not the bacteria, produce the disease symptoms. Antibodies produced against exotoxins are called antitoxins.

Botulinum toxin Botulinum toxin is a protein and neurotoxin produced by the bacterium Clostridium botulinum. Botulinum toxin can cause botulism, a serious and life-threatening illness in humans and animals. When introduced intravenously in monkeys, type A (Botox Cosmetic) of the toxin exhibits an LD50 of 40–56 ng, type C1 around 32 ng, type D 3200 ng, and type E 88 ng; these are some of the most potent neurotoxins known.

Clostridial toxins C. difficile large clostridial toxins Clostridium difficile, as all clostridia, is a toxin producing microorganism and the toxins are the main virulence factors. In the early eighties it was clear that two large toxins are produced by the bacterium and epidemiological studies have indicated that strains either produce both toxins (toxin A, TcdA, and toxin B, TcdB) or none of them.

Toxins Bacterial Toxins. Botulinum toxin, produced by the bacteria Clostridium botulinum, is the most poisonous substance known. The bacteria grows on, e.g., poorly preserved food and causes a severe form of food-poisoning (botulism).hey usually consist of an amino acid chain which can vary in molecular weight between a couple of hundred (peptides) and one hundred thousand (proteins). They may also be low-molecular organic compounds. Toxins are produced by numerous organisms, e.g., bacteria, fungi, algae and plants.

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.

- At a chemical level, there are two main types of bacterial toxins, lipopolysaccharides, which are associated with the cell wall of Gram-negative bacteria, and proteins, which are released from bacterial cells and may act at tissue sites removed from the site of bacterial growth.he processes by which protein toxins are assembled and secreted by bacterial cells are also variable. Many of the classic exotoxins are synthesized with an NH terminal leader (signal) sequence consisting of a few (1-3) charged amino acids and a stretch of (14-20) hydrophobic amino acids.
