Review Question - QID 215622

A 55-year-old presents to the Emergency Department with atraumatic knee pain, intermittent fevers, and an inability to bear weight. Inflammatory markers are significantly elevated. Given the signs and symptoms, the junior resident on call performs an arthrocentesis, which confirms septic arthritis. The patient promptly undergoes a thorough irrigation and debridement followed by hospital admission. The infectious disease team is consulted and recommends starting an antibiotic that inhibits transpeptidation by binding to D-alanyl-D-alanine residues of the bacterial cell wall. What antibiotic has this mechanism of action?
