Robert Hermann Koch (11 December 1843 – 27 May 1910) was a German physician who developed Koch's postulates. [1] 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 ...
Molecular Koch's postulates are a set of experimental criteria that must be satisfied to show that a gene found in a pathogenic microorganism encodes a product that contributes to the disease caused by the pathogen. Genes that satisfy molecular Koch's postulates are often referred to as virulence factors.
Although Koch's postulates are often inapplicable, they remain heuristic, and the authority of "fulfilling Koch's postulates" is still invoked in medical science, though often in modified form, [38] as in the identification of HIV-1 as the cause of AIDS or the identification of SARS coronavirus as the cause of SARS.

This paradigm was altered when Warren and Marshall effectively proved Koch's postulates for causation of PUD by H. pylori through a series of experiments in the 1980s; however, an extensive effort was required to convince the medical community of the relevance of their work.
As I pointed out earlier, Koch's postulates are based solely on clinical findings. They are exercises in pure laboratory science and conclusions drawn logically from them. BTW, that same source also contains the following remarkable statement: Koch's postulates also have been fulfilled in animal models of human AIDS. Chimpanzees experimentally ...
