The
human microbiota is the aggregate of
microorganisms, a
microbiome that resides on the surface and in deep layers of skin (including in mammary glands), in the saliva and oral mucosa, in the
conjunctiva, and in the gastrointestinal tracts. They include
bacteria,
fungi, and
archaea.
Micro-animals which live on the human body are excluded. The
human microbiome refers to their
genomes.
