Silkworm experiments and Vaccine Developments

He invented the cure for diseases that affected silkworms, which proved to be a boon to textile industries, Chicken Cholera, Rabies, and Anthrax in sheep.

His principles and research were used by future scientists such as Valley Radot, Frankland, Descours, Holmes, and Emile Duclaux in developing vaccines for diseases such as cholera, yellow fever, diphtheria, typhus and different strains of plague.

The Pasteur Institute was founded in 1888 to study the vaccine for rabies and research about other dangerous and contagious diseases. The Institute is known for its inventions and research in the field of microbiology, and other fields and discovered the discipline of microbiology in 1889.

To help researchers to learn and explore the most of science he established several Pasteur institutes around the world and through-out Europe especially. Since 1891, he started to establish various research institutes and hospitals for people and now there are 32 Pasteur institutes or hospitals in 29 countries around the world.

Louis Pasteur germ theory

To make people believe in the idea and effectiveness of his theory was not easy for him. There were times when his theories were considered controversial but now is considered correct.

He continuously worked to convince surgeons to believe that the germs are a cause of diseases and not ‘bad air’. He fought for his theory and During Louis Pasteur’s lifetime, it was not easy for him to convince others of his ideas, which were controversial in their time but are considered correct today.

Pasteur fought to convince surgeons that germs existed and they spread through human contact and even medical instruments. He thence states that killing these germs through sterilization and pasteurization is important and imperative.

In addition to germ theory, he also researched in virology. His intense research in for rabies, he realized that some weak kind of disease can be used as “immunization” against stronger forms of the disease.

The demise of Louis Pasteur

Louis Pasteur worked at one of the Pasteur institutes until June 1895 and then retired due to his increasingly bad health. Unfortunately due to multiple strokes, he died on 28 September 1895.

Louis Pasteur was one of the bravest and kindest souls one has encountered and he not only worked for benefits of known, but also the entire community and the world.

More than any scientist, he helped in increasing the life expectancy of people in the nineteenth and twentieth century.  His researches and are still read and referred extensively.
