Asked in PMC Practice Test 26 (2021) 2021

Which of the following statements about the systemic effect of bacterial cells are true?

Correct answer: D. None of these options is correct

  • A. Gram-negative bacteria are more likely to cause systemic effects because they lack an outer membrane which means they can infect host cells more quickly.
  • B. Gram-negative bacteria are more likely to cause systemic effects because they have an outer membrane which is supposed to protect them from antibiotics
  • C. Both Options A and B are correct
  • D. None of these options is correct

Explanation

d) None of these options is correct.This option is the most accurate. Both Option A and Option B have inaccuracies in their statements. Gram-negative bacteria do have an outer membrane, and their systemic effects are not solely due to the absence of this membrane or its protective function against antibiotics. The systemic effects of bacterial infections depend on various factors, including the pathogenicity of the bacteria, the host's immune response, and the release of bacterial toxins.
