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] In 1882, fueled by national rivalry and a language barrier, the tension between Pasteur and the younger Koch erupted into an acute ...
English: Louis Pasteur’s pasteurization experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the liquid itself. These experiments were important pieces of evidence supporting the idea of Germ Theory of Disease.
Heinrich Hermann Robert Koch (/ k ɒ x / KOKH; [1] [2] German: [ˈʁoːbɛʁt ˈkɔx] ⓘ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist.As the discoverer of the specific causative agents of deadly infectious diseases including tuberculosis, cholera and anthrax, he is regarded as one of the main founders of modern bacteriology.
Pasteur was then asked by Napoleon III to study French wineries because a large portion of French wine was contaminated. [45] Pasteur believed that heating the wine could destroy the microorganisms which had contaminated it. This process became known as pasteurization. [49] [50] Louis Pasteur's experiment to disprove spontaneous generation
Koch's postulates (/ k ɒ x / KOKH) [2] are four criteria designed to establish a causal relationship between a microbe and a disease. The postulates were formulated by Robert Koch and Friedrich Loeffler in 1884, based on earlier concepts described by Jakob Henle , and the statements were refined and published by Koch in 1890. [ 3 ]
He observed that the agent multiplied only in cells that were dividing and he called it a contagium vivum fluidum (soluble living germ) and re-introduced the word virus. [3] Beijerinck maintained that viruses were liquid in nature, a theory later discredited by the American biochemist and virologist Wendell Meredith Stanley (1904–1971), who ...
Louis Pasteur and Robert Koch were contemporaries of Cohn, and are often considered to be the fathers of modern microbiology [16] and medical microbiology, respectively. [18] Pasteur is most famous for his series of experiments designed to disprove the then widely held theory of spontaneous generation , thereby solidifying microbiology's ...
The first culture media was liquid media, designed by Louis Pasteur in 1860. [2] This was used in the laboratory until Robert Koch's development of solid media in 1881. [3] Koch's method of using a flat plate for his solid media was replaced by Julius Richard Petri's round box in 1887. [2]
