To find a solution to a horrifying and horrifying illness Pasteur Experiments were conducted with rabbits to transfer infectious pathogens from animal to animal. He dried the spinal cord of the infected animal to reduce the effects of the invisible drug, but later realized that instead of reducing the effects of the drug, his treatment actually neutralized it. rice field.
