New Delhi metallo-beta-lactamase-1 (NDM-1) is a bacterial enzyme that renders the bacteria resistant to a variety of beta-lactam
antibiotics. A 20-year-old man was hospitalized several times for surgical treatment and complications caused by a right-sided
vestibular schwannoma. Although the patient acquired several multidrug-resistant infections, this study focuses on the NDM-
1-producing Acinetobacter spp. infection. As it was resistant to all antimicrobials tested, the medical team developed a 20-day
regimen of 750mg/day metronidazole, 2,000,000IU/day polymyxin B, and 100mg/day tigecycline. The treatment was effective,
and the patient recovered and was discharged from the hospital.
