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 ...
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.
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]
Based on these experiments, he devised criteria for establishing a causal link between a microorganism and a disease and these are now known as Koch's postulates. [18] Although these postulates cannot be applied in all cases, they do retain historical importance to the development of scientific thought and are still being used today. [19]
After years of waiting for a bigger and better College Football Playoff, the moment has finally arrived.The bracket is set and the games are here. The inaugural 12-team field has a few surprises ...
These postulates were first used in the discovery that Mycobacteria species cause tuberculosis. [62] However, Koch's postulates cannot usually be tested in modern practice for ethical reasons. Proving them would require experimental infection of a healthy individual with a pathogen produced as a pure culture.
