Microbiota (microorganisms) refers to the bacterial population that resides in and on the body. This includes bacteria on the skin, in the gut, and in other parts of the body. The term microbiome (microbial community) is used to describe all of the microbial populations within an environment, such as within the human gut.
The microbiota and microbiome are important for many reasons. The microbiota helps protect against infection, maintain balance within the gut ecosystem, and perform functions that are essential for human health. The microbiome has been linked with a variety of disorders, including obesity, diabetes, asthma, and cancer.
research on microbiota and microbiome is ongoing, and scientists are still learning about the roles these tiny organisms play in human health and disease. However, studies to date suggest that maintaining a healthy microbiota is important for overall health.
