WebClostridium botulinum produces Botulinum neurotoxins (BoNTs), causing a rare but potentially deadly type of food poisoning called foodborne botulism. This review aims to provide information on the bacterium, spores, toxins, and botulisms, and describe the use of physical treatments (e.g., heating, pressure, irradiation, and other emerging technologies) … 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. 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 immunity.

WebThe binding of the exotoxin and antibody forms an antigen-antibody interaction and the exotoxins are targeted for destruction by the immune system. If this interaction does not happen, the exotoxins bind to the exotoxin receptors that are on the cell surface and causes death of the host cell by inhibiting protein synthesis. WebDec 24, 2024 · The antibody response is crucial for preventing many viral infections and may also contribute to the resolution of an infection. When a vertebrate is infected with a virus, antibodies are produced against many epitopes of multiple virus proteins. A subset of these antibodies can block viral infection by a process called neutralization.
