Pasteur also worked to create a vaccine for anthrax. In his experiment, Pasteur gave 25 animals two shots of an anthrax vaccine he had created with weakened anthrax bacteria. After he gave both rounds of the vaccine to these animals, he injected them with live anthrax bacteria.
Why Anthrax is a biological weapon?
Anthrax as a weapon Anthrax is one of the most likely agents to be used because: Anthrax spores are easily found in nature, can be produced in a lab, and can last for a long time in the environment. Anthrax makes a good weapon because it can be released quietly and without anyone knowing.
How does anthrax kill?
Deadly toxins The two toxins produced by anthrax, called lethal toxin and edema toxin, damage many types of cells, but it was thought that their effects on endothelial cells, which line blood and lymph vessels, were what made anthrax so lethal.
