What term describes bacteria flora found in skin creases that require friction with a brush to remove?

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

Answer: (A)

The situation is about how bacteria on the skin are categorized into resident and transient flora. The bacteria that live in skin creases and deeper layers are considered resident flora; they form part of the normal skin microbiota and aren’t easily removed by simple washing. They require mechanical action, like friction from brushing or scrubbing, to be dislodged. Transient flora, by contrast, sit on the surface and can be washed away more readily. Opportunistic organisms are those that can cause disease when defenses are weak, and pathogenic describes organisms that can cause disease in general, but the clue points to the normal, firmly established skin inhabitants. So the best fit is resident flora.
