Description
This quiz covers Koch's postulates, a set of criteria used to establish the causative relationship between a microorganism and a disease. The postulates involve isolating the microorganism from a diseased host, growing it in pure culture, reinoculating it into a healthy host, and reisolating it from the diseased host.
