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

Option D is the correct answer.

Detailed Explanation

One of Koch's postulates states that the same pathogen must be re-isolated from the experimentally inoculated diseased host. Therefore, the statement 'The pathogen must not be re-isolated from the new host' is incorrect.

Hint

Recall the full sequence of Koch's postulates, especially the final step involving re-isolation.
