what is the difference between transient microbes and resident microbes ?

Transient microbes are microbes that temporarily reside on the skin or other surfaces of the body and can be easily removed through washing or other forms of hygiene. They do not permanently colonize the body and are typically harmless.

Resident microbes, on the other hand, are microbes that are permanent or long-term inhabitants of the body and establish a stable, beneficial relationship with the host. These microbes often play a role in maintaining the health of the body and are more difficult to remove than transient microbes.

Overall, the main difference between transient and resident microbes lies in their longevity and relationship with the host organism.
