    Koch had transformed bacteriology by introducing the technique of pure culture, whereby he established the microbial cause of the disease anthrax (1876), had introduced both staining and solid culture plates to bacteriology (1881), had identified the microbial cause of tuberculosis (1882), had incidentally popularized Koch's postulates for ...

  4. Molecular Koch's postulates - Wikipedia

    en.wikipedia.org/wiki/Molecular_Koch's_postulates

    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.

    In 1890, Koch created what he called his four postulates in determining if a microorganism is the causse of a disease. His four original criteria were: [71] 1.The microorganism must be present in every case of the disease. 2. The microorganism must be isolated from the diseased host and grown as a pure culture in the laboratory 3.

  7. Microbial pathogenesis - Wikipedia

    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.

  8. Microorganism - Wikipedia

    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]

  9. Medical microbiology - Wikipedia

    He developed a series of criteria around this that have become known as the Koch's postulates. [7] A major milestone in medical microbiology is the Gram stain. In 1884 Hans Christian Gram developed the method of staining bacteria to make them more visible and differentiated under a microscope. This technique is widely used today. [8]
