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 None of these
C The pathogen from the pure culture must cause the disease when inoculated into a healthy, susceptible host
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 pathogen must be re-isolated from the experimentally infected host and shown to be the same as the original pathogen.' Therefore, the statement 'The pathogen must not be re-isolated from the new host' is incorrect.

Hint

Remember the steps involved in verifying a pathogen's link to a disease according to Koch. What happens after the healthy host gets infected?
