How is a microbiome defined?

• A. A collection of viruses in the body
• B. A collection of microorganisms in a specific environment
• C. A type of pathogenic microorganism
• D. A breeding ground for bacteria

Answer: (B)

The definition of a microbiome refers specifically to a collection of microorganisms, which includes bacteria, archaea, fungi, viruses, and even protozoa, that reside in a particular environment, such as the human body. This collection plays a vital role in maintaining health, influencing the immune system, aiding in digestion, and contributing to overall physiological functions. Microbiomes can vary significantly between different environments, such as the gut, skin, or oral cavity, each hosting unique microbial communities that are adapted to their specific environments. This diversity is essential for the proper functioning of ecosystems and the host organism. The concept emphasizes the interaction between these microorganisms and their environment, highlighting the importance of the community of microorganisms rather than focusing on individual species. In contrast, definitions that center solely on viruses, pathogenic microorganisms, or breeding grounds do not fully encompass the complexity and diversity represented by a microbiome. A microbiome is not limited to harmful organisms, nor is it merely a collection of viruses or bacteria, but rather a diverse and dynamic community of microorganisms with a wide range of functions and interactions.
