Epidemiology and Genomic Characteristics of Bloodstream Infection Caused by Carbapenem-Resistant Klebsiella pneumoniae With Decreased Susceptibility to Aztreonam/Avibactam in China

Abstract excerpt

Aztreonam/avibactam (AZA), as one of the novel β-lactamases and β-lactamase inhibitor combinations, is considered to be a promising option for bloodstream infection (BSI) of carbapenem-resistant Klebsiella pneumoniae (CR-Kp). However, decreased susceptibility of AZA activity in Enterobacterales has been reported. The aim of this study was to identify the mechanisms of BSI CR-Kp with decreased susceptibility of...
