Abstract:
Ceftolozane/tazobactam (C/T) is a novel β-lactam/β-lactamase inhibitor combination antibiotic approved by the US Food and Drug Administration for the treatment of complicated intra-abdominal and urinary tract infections due to Gram-negative bacteria, particularly extended-spectrum β-lactamase-producing Enterobacteriaceae and multidrug-resistant (MDR) Pseudomonas aeruginosa strains. Here we report a case of MDR P. aeruginosa skin and soft-tissue infection successfully treated with C/T.
