Botulinum toxin vs tetanus toxin
WebBotulinum toxins (seven related toxins), the staphylococcal enterotoxins (also seven different toxins), diphtheria and tetanus toxin are well-known examples of bacterial toxins.

WebTetanus toxin is one of the most potent known poisons on a weight basis because of its absolute neurospecificity and enzymatic function at the site of action. 105 As little as 1 ng/kg will kill a mouse; 0.3 ng/kg will kill a guinea pig. 106 The estimated minimum human lethal dose is less than 2.5 ng/kg. 106 Various species have different levels ... WebTetanus toxin, like botulinum toxin type A, blocks cholinergic synaptic transmission at the central and peripheral nervous systems. Nevertheless, the diseases induced by the two toxins are different since tetanus toxin induces a spastic paralysis and botulinum toxin elicits a flaccid paralysis. Thus …
Tetanus toxin (TeNT) is an extremely potent neurotoxin produced by the vegetative cell of Clostridium tetani in anaerobic conditions, causing tetanus. It has no known function for clostridia in the soil environment where they are normally encountered. It is also called spasmogenic toxin, tentoxilysin, tetanospasmin or, … See more Tetanus toxin spreads through tissue spaces into the lymphatic and vascular systems. It enters the nervous system at the neuromuscular junctions and migrates through nerve trunks and into the central nervous system (CNS) … See more The mechanism of TeNT action can be broken down and discussed in these different steps: Transport Specific … See more The clinical manifestations of tetanus are caused when tetanus toxin blocks inhibitory impulses, by interfering with the release of neurotransmitters, including glycine and gamma-aminobutyric acid.
