Questions: Adherence of the causative agent to a target is necessary to establish infection; colonization is a prerequisite for the production of infectious disease. True False

The answer is True: Adherence of the causative agent to a target is necessary to establish infection; colonization is a prerequisite for the production of infectious disease.

Explanation:

• Adherence refers to the ability of a microorganism to attach to host cells or tissues. This is a critical first step in the establishment of an infection because it allows the pathogen to remain in the host environment and resist being flushed out by bodily fluids.
• Colonization is the process by which a microorganism establishes itself on a host, often leading to the growth and multiplication of the pathogen. This is necessary for the development of an infectious disease, as it allows the pathogen to reach sufficient numbers to overcome host defenses and cause symptoms.
• Without adherence and colonization, a pathogen is unlikely to successfully infect a host and cause disease. Therefore, both adherence and colonization are essential steps in the pathogenesis of infectious diseases.
