Koch's postulate

Koch's postulate

The criterion used in proving an organism is the cause of a disease or lesion: the microorganism in question is regularly found in the lesions of the disease; pure cultures can be obtained from it. When inoculated into susceptible animals, pure cultures can reproduce the disease or pathological condition; and the organism can be obtained again in pure culture from the inoculated animal.
