This link is known as the germ theory. Pasteur was studying these connections by injecting chickens with chicken cholera bacteria and trying to find the site of the infection. During this experiment, Pasteur asked his assistant to inject a batch of chickens with a fresh sample of the chicken cholera bacteria. The assistant forgot and went on vacation. When Pasteur’s assistant returned a month later, he injected the chickens with the left out bacteria and the chickens survived. Pasteur then injected the same chickens with a fresh sample of chicken cholera and the chickens did not get sick. Therefore the chickens developed an immunity to the bacteria. From this experiment, Pasteur is credited with the first laboratory developed vaccine. Since veterinarians in Paris were becoming concerned about the number of rabid dogs running wild in the streets, Louis Pasteur performed a study on rabies. Pasteur took samples from dead dogs and injected other animals with rabies. Then he tried to determine the site and cause of the infection so he could find a treatment or develop a vaccine. Pasteur was successful in developing a vaccine in 1885 and opened an institute is Paris to treat
