Bacterial flora attached loosely on the skin and removed with relative ease are called

• A. Transient
• B. Resident
• C. Pathogenic
• D. Opportunistic

Answer: (A)

Bacteria on the skin fall into two groups: transient and resident. Transient flora are picked up from the environment and sit loosely on the surface, so they can be removed with relative ease by washing or rubbing the skin. They’re not permanent residents and can include organisms you encounter through contact. Resident flora, by contrast, are more firmly attached in the skin’s deeper layers and follicles and aren’t easily washed away. The description given matches transient flora.
