Which is considered the most resistant bacterial structure/component?
Show answer and explanation
Correct answer: B. Biofilm
- A. Planktonic bacteria are far more susceptible to antimicrobials than their biofilm-embedded counterparts.
- B. Correct. The biofilm's extracellular matrix shields bacteria, dramatically increasing resistance to antimicrobials and host defenses.
- C. The cell wall is a target of many antibiotics, not the most resistant structure overall.
- D. A plasmid can carry resistance genes but is not itself the 'most resistant component.'
