Verified step by step guidance

Understand the context of Koch's original postulates, which were developed to establish a causative relationship between a microbe and a disease.

Recognize the limitations of Koch's original postulates, such as the inability to apply them to all pathogens, especially those that cannot be cultured in the lab.

Learn about molecular Koch's postulates, which were developed to address these limitations by incorporating genetic and molecular techniques.

Consider the advancements in genetic technology and microbial studies that have occurred since Koch's time, allowing for more detailed investigations into pathogenic mechanisms.

Identify the statement that does not align with the reasons for developing molecular Koch's postulates, focusing on the ability to culture pathogens in the lab as a key limitation of the original postulates.
