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.
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 ...
Falkow is known as the father of the field of molecular microbial pathogenesis. [1] He formulated molecular Koch's postulates, which have guided the study of the microbial determinants of infectious diseases since the late 1980s. [2] Falkow spent over 50 years uncovering molecular mechanisms of how bacteria cause disease and how to disarm them. [1]
Microbial pathogenesis is a field of microbiology that started at least as early as 1988, with the identification of the triune Falkow's criteria, aka molecular Koch's postulates.
This assists in identifying new virulence factors for the infectivity of H. pylori on the molecular level. [57] [58] 2001 Chan et al. show in a randomized control trial that eradication of H. pylori even prevents bleeding from ulcers that is caused by aspirin and non-steroidal anti-inflammatory drugs.

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.
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.

In 1890, Robert Koch developed a list of criteria to determine whether a specific bacterium was the cause of a given disease. Today we refer to that criterion as Koch’s postulates. The criteria to determine a true pathogen according to Koch’s postulates includes:
