Used to prove the causative relationship between most bacterial pathogens and their respective diseases Molecular version of Kochs postulate 1 the genefactor should be present in all pathogenic strains of the organism and absent from non pathogenic strains.

The steps were first described by Robert Koch in 1882 and later added to by Erwin F Smith in 1905. Robert Koch and Kochs postulates. - same microorganism must be isolated again from the diseased.

Robert Kochs postulates published in 1890 are a set of criteria that establish whether a particular organism is the cause of a particular disease. The microorganism must be found in abundance in all organisms suffering from the disease but should not be found in.
