et al.

Abstract: We aimed to evaluate the in vitro antibacterial effects of combination of cefepime/avibactam against carbapenem-resistant Klebsiella pneumonia (CRKP) and explore the resistance mechanism of FEP/AVI. Patients and Methods: This study explored the in vitro antibacterial activities of ceftazidime/avibactam (CAZ/AVI) and cefepime/ avibactam (FEP/AVI) against 40 and 76 CRKP clinical isolates. Proteomics and metabolomics were employed to investigate the resistance mechanisms of CRKP to FEP/AVI. Results: FEP/AVI (MIC … Show more
