The French Louis Pasteur (1822–1895) and German Robert Koch (1843–1910) are the two greatest figures in medical microbiology and in establishing acceptance of the germ theory of disease (germ theory). [1]
Bacteria could be seen under microscope, and cultured on agar plates. In 1890, Louis Pasteur declared "tout virus est un microbe": "all infectious diseases are caused by microbes". In 1892, Dmitri Ivanovsky discovered that the cause of tobacco mosaic disease could pass through Chamberland's porcelain filter. Infected sap, passed through the ...

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.

By the end of that decade, the miasma theory was struggling to compete with the germ theory of disease. Viruses were initially discovered in the 1890s. Eventually, a "golden era" of bacteriology ensued, during which the germ theory quickly led to the identification of the actual organisms that cause many diseases. [2]
