DOI: 10.1016/j.ijantimicag.2018.07.027
Abstract: In Pseudomonas aeruginosa (P. aeruginosa) collected from cystic fibrosis (CF) patients, 24% resistance to ceftazidime-avibactam in isolates negative for carbapenemases and extended-spectrum β-lactamases (ESBLs) has previously been observed. The current study aimed to unravel the… read more here.
