WebThe Harvard strain of Clostridium tetani is grown in a fermentor for about a week using a semisynthetic medium. This leads the bacteria to lyze and release the toxin obtained in the supernatant. This method yielded about 60-80 Lf/ml. This yield is then filtered and detoxified using formaldehyde. WebMar 31, 2024 · Toxins: Plasmid coded Interestingly, all toxin-producing strains of C. tetani possess a large plasmid, which encodes for the synthesis of the toxin. Loss of the plasmid converts the cell to an avirulent, non-toxin- producing organism. Tetanus toxin is generated in living bacteria, and is released when the bacteria lyse, such as during spore ...
