A microbiome is the community of microorganisms that can usually be found living together in any given habitat. It is the collection of all microorganisms, such as bacteria, fungi, viruses, and their genes, that naturally live on our bodies and inside us. The microbiome not only refers to the microorganisms involved but also encompasses their theatre of activity, which results in the formation of specific ecological niches. The human microbiome is the aggregate of all microbiota that reside on or within human tissues and biofluids along with the corresponding anatomical sites in which they reside, including the skin, mammary glands, seminal fluid, uterus, ovarian.

The microbiome is a dynamic and changing community of microorganisms that live in or on a particular part of the body, such as the skin or gastrointestinal tract. These groups of microorganisms are dynamic and change in response to a host of environmental factors, such as exercise, diet, medication, and other exposures. The microbiome consists of microbes that are both helpful and potentially harmful, and most are symbiotic, where both the human body and microbiota benefit. In a healthy body, pathogenic and symbiotic microbiota coexist without problems.

The microbiome is a critical part of human health, and research on the microbiome has become a topic of great scientific and public interest. The field of microbiome research has evolved rapidly over the past few decades, and a clear commonly agreed definition of the term “microbiome” is still lacking. However, the microbiome is generally defined as the community of microorganisms (such as fungi, bacteria, and viruses) that exists in a particular environment.
