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 .
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 ...
John Snow (15 March 1813 – 16 June 1858 [1]) was an English physician and a leader in the development of anaesthesia and medical hygiene.He is considered one of the founders of modern epidemiology and early germ theory, in part because of his work in tracing the source of a cholera outbreak in London's Soho, which he identified as a particular public water pump.
1861 – Louis Pasteur discovers the Germ Theory; 1867 – Lister publishes Antiseptic Principle of the Practice of Surgery, based partly on Pasteur's work. 1870 – Louis Pasteur and Robert Koch establish the germ theory of disease. 1878 – Ellis Reynolds Shipp graduates from the Women's Medical College of Pennsylvania and begins practice in ...
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.
Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
Germ theory denialism is the pseudoscientific belief that germs do not cause infectious disease, and that the germ theory of disease is wrong. [1] It usually involves arguing that Louis Pasteur 's model of infectious disease was wrong, and that Antoine Béchamp 's was right.
This began the path to germ specificity within the theory. [49] 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 ...
