Louise Pasteur, a French woman who was neither a doctor nor a veterinarian, became known for helping to find a vaccine for rabies. He began the study of rabies when two rabid dogs were introduced into his laboratory. One of the dogs suffered from the mute form of the disease: his lower jaw was hanging, he was foaming at the mouth and his eyes looked rather vacant. The other dog was furious: he broke, bit any object handed to him and uttered frightening howls (McCoy 65). According to studies already observed, rabies was transmitted by the bite of a rabid animal, and that the incubation period varied. from a few days to several months. Beyond that, nothing specific was known. Then Mr. Bouley, professor of veterinary science, noticed a germ or organism in the saliva of a rabid dog. Pasteur confirmed Bouley's findings by collecting mucus from a child bitten by a fast dog and injecting it into rabbits. The results of this experiment resulted in the death of all the rabbits within 36 hours. This experiment established two facts: an organism was present in the saliva of rabid animals and it could be transmitted to another animal or a human being through a bite (McCoy 66). Further research led Pasteur to the conclusion that the rabies organism was located in other parts of the infected animal's body than its saliva. Experiments on the skulls of rabid dogs showed that the brains contained the rabies virus. Pasture then grew certain viruses from the brains of several rabid dogs. The virus was then injected into rabbits. In any case, rabies would appear within 14 days (McCoy 67). After several experiments, Pasteur developed a vaccine against rabies. He first demonstrated to doctors and veterinarians that rabies could be grown from the brains of living dogs. Pasteur successfully proved that his rabies vaccine could now be administered safely and that animals could be vaccinated against the disease. Once the vaccine was perfected, Pasteur began researching a vaccine for human patients. After considerable research and patients, Pasteur finally developed a human vaccine against rabies. The vaccine would be administered through a system of inculcations and would prevent disease in a patient recently bitten by a fast dog (McCoy 67). This system became known as the Pasteur treatment of rabies. Although there is still no cure for this disease in animals or humans, the disease can be prevented if vaccines are administered early enough..
