QuestionSBA
QuestionChoice
Aminoglycosides such as gentamicin work by binding to ribosomes to inhibit bacterial protein synthesis. This does not describe the mechanism of action of ciprofloxacin. Quinolones such as ciprofloxacin work by inhibiting bacterial DNA synthesis.

e
Inhibition of protein synthesis
QuestionChoice
Programmed cell death of bacteria is not a recognised method of bacterial destruction by conventional antibiotics. This does not describe the mechanism of action of ciprofloxacin. Quinolones such as ciprofloxacin work by inhibiting bacterial DNA synthesis.

d
Programmed cell death of bacteria
QuestionChoice
Bacterial protein synthesis inhibition describes the mechanism of action of tetracycline, macrolide and aminoglycoside antibiotics. By contrast, quinolones such as ciprofloxacin work by inhibiting bacterial DNA synthesis.

c
Bacterial protein synthesis inhibition
QuestionChoice
Quinolones (including ciprofloxacin), sulphonamides and nitroimidazoles work by inhibiting bacterial DNA synthesis. This answer is therefore correct.

Inhibition of nucleic acid synthesis
QuestionChoice
Inhibition of bacterial cell wall synthesis describes the mechanism of action of penicillins and cephalosporins. By contrast, quinolones such as ciprofloxacin work by inhibiting bacterial DNA synthesis.

A 57 year old man is prescribed ciprofloxacin for an infected diabetic ulcer. The GP explains that ciprofloxacin is a member of the quinolone family of antibiotics.

Which of the following best describes the mechanism of action of ciprofloxacin?
a
