摘要
The in vitro antibacterial activities of ceftazidime-avibactam and comparator agents were evaluated using reference broth microdilution methods against 1,743 Pseudomonas aeruginosa isolates collected in 2014 from 69 U.S. medical centers, representing each of the nine census regions. Ceftazidime-avibactam demonstrated potent activity against P. aeruginosa, including many isolates not susceptible to ceftazidime, meropenem, and piperacillin-tazobactam. In each of the nine census regions, ceftazidime-avibactam demonstrated the highest percentage of susceptible isolates.
