Koch's rule is a set of scientific verification methods put forward by German bacteriologist robert koch (1843 ~ 19 10), which is used to verify the relationship between bacteria and diseases, and is regarded as the golden rule for the identification of infectious disease pathogens by later generations.
It laid a foundation for the establishment of systematic research methods of pathogenic microbiology and made it an independent discipline. As a research method, it may have been more or less impacted by modern research methods and become meaningless; But as a research idea, it is of great significance for people to establish strict thinking habits.
Robert koch's law was transplanted and became the classic law of plant pathology.
1 and * * *: organisms suspected to be pathogens must always be found on diseased plants.
2. Separation: The organism must be separated from the diseased plants and cultivated in the culture medium, that is, only this organism is cultivated without other organisms.
3. Inoculation: Inoculating the above pure culture on healthy plants causes the same diseases as the original specimens.
4. Re-separation: Re-separation of the diseased plants caused by the above inoculation to obtain a pure culture, which is completely consistent with the pure culture used for inoculation.
