Which of the following is a primary goal for scientists studying the human microbiome?

• A. To understand how microbial communities influence human health and disease
• B. To develop antibiotics that target all microbes indiscriminately
• C. To eliminate all bacteria from the human body
• D. To prove that viruses are the only important microorganisms in humans

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the definition of the human microbiome, which refers to the collection of all microorganisms, including bacteria, viruses, fungi, and their genetic material, living in and on the human body.
2. Step 2: Recognize that scientists studying the human microbiome aim to explore the relationships between these microbial communities and their human host, particularly how they affect health and disease.
3. Step 3: Evaluate the options by considering the goals of microbiome research: it is not about eliminating all microbes or targeting all microbes indiscriminately, as many microbes are beneficial or essential for normal bodily functions.
4. Step 4: Note that the study of the microbiome includes bacteria, viruses, and other microorganisms, so focusing only on viruses is too narrow and does not represent the primary goal.
5. Step 5: Conclude that the primary goal is to understand how microbial communities influence human health and disease, which can lead to improved diagnostics, treatments, and preventive strategies.
