A toxoid is an inactivated toxin (usually an exotoxin) whose toxicity has been suppressed either by chemical or heat treatment, while other properties, typically immunogenicity, are maintained. [1] Toxins are secreted by bacteria, whereas toxoids are altered form of toxins; toxoids are not secreted by bacteria.
Tetanus vaccine, also known as tetanus toxoid (TT), is a toxoid vaccine used to prevent tetanus. [2] During childhood, five doses are recommended, with a sixth given during adolescence. [2] After three doses, almost everyone is initially immune, [2] but additional doses every ten years are recommended to maintain immunity. [3]
Exotoxins have been used to produce vaccines. This process involves inactivating the toxin, creating a toxoid that does not induce toxin-related illness and is well tolerated. [8] A widely used toxoid vaccine is the DPT vaccine, which is usually administered in multiple doses throughout childhood with adjuvants and boosters for long-term ...
The term toxoid refers to vaccines which use an inactivated toxin produced by the pathogen which they are targeted against to generate an immune response. In this way, the toxoid vaccine generates an immune response which is targeted against the toxin which is produced by the pathogen and causes disease, rather than a vaccine which is targeted ...
Anti-tetanus immunoglobulin, also known as tetanus immune globulin (TIG) and tetanus antitoxin, is a medication made up of antibodies against the tetanus toxin. [1] It is used to prevent tetanus in those who have a wound that is at high risk, have not been fully vaccinated with tetanus toxoid, or have HIV/AIDS.
Microbial toxins are toxins produced by micro-organisms, ... When the toxoid is introduced to the body in a vaccine, ... If zearalenone is consumed during pregnancy ...
The toxin forms an ion channel in the membrane that is nonspecific for Na +, K +, Ca 2+, and Cl − ions. [32] There is a consensus among experts that this new channel is involved in the translocation of the toxin's light chain from the inside of the vesicle to the neuron cytosol, but the mechanism is not well understood or agreed upon.
[6] [1] Tetanospasmin ("tetanus toxin") is a potent toxin with an estimated lethal dose less than 2.5 nanograms per kilogram of body weight, and is responsible for the symptoms of tetanus. [6] [1] Tetanospasmin spreads via the lymphatic system and bloodstream throughout the body, where it is taken up into various parts of the nervous system. [6]
