Question

Which of the following is not true about Koch's postulates?
Options
A The specific pathogen must be isolated from the diseased host and grown in pure culture.
B The pathogen from the pure culture must cause the disease when inoculated into a healthy, susceptible host.
C The pathogen must be present in all cases of the disease.
D The pathogen must <i>not</i> be re-isolated from the experimentally infected host.
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Koch's postulates state that the specific pathogen must be re-isolated from the experimentally infected host and identified as identical to the original pathogen. Therefore, stating that it must not be re-isolated is incorrect. Options A, B, and C are actual components of Koch's postulates.

Hint

Remember that one of the crucial steps in Koch's postulates involves confirming the pathogen's presence and identity after experimental infection.
