Common questions about Microbiota

What does Microbiota mean in medicine?
The full collection of microbes (bacteria, fungi, virus, etc.) that naturally exist within a particular biological niche such as an organism, soil, a body of water, etc. This definition is taken from the National Library of Medicine's MeSH (Medical Subject Headings) 2026 release, which is the standard vocabulary used to index PubMed and most medical literature.
Is Microbiota known by any other names?
Yes. Microbiota is also referred to as Microbiotas, Microbial Community, Community, Microbial, Microbial Communities in different clinical, research and patient-facing contexts. The MeSH descriptor groups all of these synonyms under a single canonical concept so research and records stay consistent.
