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 ...
The Vertifolia effect is a well documented phenomenon in the fields of plant breeding and plant pathology. It is characterized by the erosion of a crop’s horizontal resistance to disease during a breeding cycle due to the presence of strong vertical resistance, characterized by the presence of R genes. This effect was observed in late blight ...
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.
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.
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.
These reported cases reveal newly identified plant hosts for the pathogen N. sphaerica that have been validated through Koch’s postulates. [8] [10] The fungus causes a progressively fatal leaf spot diseases of a range of plants including blueberry (Vaccinium corymbosum), [8] licorice (Glycyrrhiza glabra), [9] and Wisteria sinensis (Chinese ...
Nonetheless, he was unable to complete Koch's postulates to determine the causal pathogen of the disease. Then, in 1895, F.C. Stewart observed wilt in sweet-corn plants in Long Island , NY. After completion of Koch's postulates with the bacteria in sweet corn, Stewart gave an accurate account of the symptoms and named the pathogen Pseudomonas ...
