Transient microbes are microorganisms that are only temporarily present on or in the human body. They are typically acquired from external sources, such as the environment or other individuals, and do not permanently colonize the body like resident microbes. Transient microbes can include bacteria, viruses, fungi, and other microorganisms that may be harmless or pathogenic. They are typically found on the skin, in the gastrointestinal tract, and in other body cavities, but are constantly being shed and replaced through natural processes.
