Koch's postulates state that the microbe must be present in every case of the disease, it must be isolated from the host and grown in pure culture, the cultured microbe should produce the same disease when introduced into a healthy host, and the microbe should be recovered from the experimentally infected host. Yersinia, the causative agent of plague, can be isolated from sick patients, grown in pure culture, and has been shown to produce the same disease when introduced into a healthy host, thus satisfying Koch's postulates.
