Question

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 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 not 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 specific pathogen must be re-isolated from the new experimental host that became diseased. Therefore, option D, which says it 'must not be re-isolated,' is incorrect.

Hint

Recall all four of Koch's original postulates, especially the final step involving re-isolation.
