[49] [56] But, Pasteur discovered Pébrine and flacherie were separate diseases. Pasteur claimed bacteria within the silkworms' intestinal track caused flacherie. He then used a microscope to sort which eggs were infected and which were not. This was an effective way of discarding the diseased eggs so these worms would not enter the population.
The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or "germs" can cause disease. These small organisms, which are too small to be seen without magnification, invade animals, plants , and even bacteria .

Although Pasteur died in 1895, eventually over thirty official Pasteur Institutes opened across the globe. [26] Pasteur's team had planned in 1885 to open a rabies-treatment facility in St. Louis, Missouri, and an American Pasteur Institute in New York City, but the plans were abandoned, and America has never hosted an official Pasteur ...
The discovery of RNA in the particles was important because in 1928, Fred Griffith (c. 1879 –1941) provided the first evidence that its "cousin", DNA, formed genes. [18] In Pasteur's day, and for many years after his death, the word "virus" was used to describe any cause of infectious disease.
Pasteur's work on fermentation later led to his development of the germ theory of disease, which put the concept of spontaneous generation to rest. [1] Although the fermentation process had been used extensively throughout history prior to the origin of Pasteur's prevailing theories, the underlying biological and chemical processes were not ...
