what were louis pasteur's most significant findings with infectious diseases?

Question

and for what diseases did he create vaccines for?

Answer 1

Pasteur's most significant work with infectious disease is his work on the germ therory of disease. This therory proposes that microorganisms are the cause of many diseases. While Pasteur was not the first to propose germ theory (Girolamo Fracastoro, Agostino Bassi, Friedrich Henle and others had suggested it earlier), he developed it and conducted experiments that clearly indicated its correctness and managed to convince most of Europe it was true. Today he is often regarded as the father of germ theory and bacteriology, together with Robert Koch.

Pasteur created vaccines for rabies and anthrax as well as worked on a vaccine for smallpox. While he did create a vaccine for smallpox, Edward Jenner is credited with the creation of the smallpox vaccine.

Answer 2

He made vaccines for rabies and anthrax. He demonstrated that germs caused disease. And he showed that heating up liquids killed germs in them, preventing spoilage: i.e., he invented pasteurization.

Pasteurization of milk significantly cut infant mortality. Remember that in case you ever run into anyone who extols drinking raw milk.
