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 ...
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 ]
Louis Pasteur's contemporary Robert Koch devoted much of his scientific study to discovering certain pathogens and connecting them to specific diseases. These scientists were often in competition with one another and so the Koch-Pasteur rivalry is a well-known part of germ theory's history.
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.
A representation by Robert Seymour of the cholera epidemic depicts the spread of the disease in the form of poisonous air.. The miasma theory was the predominant theory of disease transmission before the germ theory took hold towards the end of the 19th century; it is no longer accepted as a correct explanation for disease by the scientific community.
Pasteur created several vaccines over the course of his lifetime. His work prior to rabies involved attenuation of pathogens, but not through serial passage. In particular, Pasteur worked with cholera and found that if he cultured bacteria for long periods of time, he could create an effective vaccine.
They rely heavily on the postulates of Koch (formulated in 1884) and on the work of Louis Pasteur (1822–1895). Changing perceptions have altered treatment models. The hypotheses have sought to establish both in caries and in periodontitis a relation between pathogen virulence , environmental considerations, plaque biofilm structure and the ...
1876 – Demonstration that microbes can cause disease-anthrax (Robert Koch) 1877 – Mast cells (Paul Ehrlich) 1878 – Confirmation and popularization of the germ theory of disease (Louis Pasteur) 1880 – 81 Theory that bacterial virulence could be attenuated by culture in vitro and used as vaccines.
