Louis Pasteur, a French chemist and microbiologist in the
1800’s, began his study of rabies when two dogs infected with
rabies were brought to his laboratory. One of the dogs suffered
from the dumb form of the disease: his jaw hung low, he foamed
at the mouth, and he had a vacant look in his eyes. The other
dog suffered from the viscous form of the disease: he let out
terrifying howls, he snapped, and he bit at any object that came
close to him. Through his research Pasteur learned that the
rabies germ/organism in saliva could pass to other animals and
people through an infected bite. Using this information, Pasteur
grew rabies germs/organisms from infected animals and then
weakened it, by drying it out, to develop the first vaccine for
rabies. (Pasteur) Back then, Pasteur was considered a chemist
and microbiologiest, today he would be considered a research
veterinarian. Veterinarians ensure that animals are healthy and
treated ethically when receiving care, that they cannot transmit
potentially fatal disease
