Transient flora are defined as what?

• A. Colonize the host for short periods of time, ranging from hours to weeks.
• B. Establish life-long residence.
• C. Always present on the skin.
• D. Found only in soil.

Answer: (A)

Transient flora are microorganisms that briefly inhabit the host after contact with the environment or another person. They establish a short-lived presence on the skin or mucous membranes, lasting from hours up to a few weeks, but they do not become a permanent, resident population. This distinguishes them from resident flora, which form a stable, long-term part of the microbiota. Because their stay is temporary, routine hygiene and washing can remove them, whereas resident flora remain part of the normal microbiome. They’re not limited to soil or always present on the skin; they’re simply the fleeting organisms acquired from the surrounding environment.
