|
Definition

2.) produce acids
3.) produce bacteriocins |

1.) Same pathogen must be present in every case of the disease
2.) Pathogen must be isolated from the diseases host and grown in pure culture
3.) Pathogen from the pure culture must cause the disease when it is inoculated into a healthy susceptible lab animal
4.) Pathogen must be isolated from inoculated animal and must be shown to be the original animal |
