Which macrolide antibiotic inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit?
Correct answer: C. Erythromycin
- A. Enrofloxacin
- B. Amikacin
- C. Erythromycin
- D. Sulfadiazine
Explanation
Erythromycin binds the 50S subunit and interferes with bacterial translocation during protein synthesis. Amikacin acts at the 30S subunit, enrofloxacin inhibits DNA gyrase, and sulfadiazine interferes with folate synthesis.
