Antimicrobial Susceptibility Trends Among Gram-Negative Bacilli Causing Bloodstream Infections: Results from the China Antimicrobial Resistance Surveillance Trial (CARST) Program, 2011–2020

Abstract

The rapid spread of carbapenem-resistant <i>K. pneumoniae</i> has been serious in recent years. Conversely, the prevalence of ESBL-producing isolates was decreased. Carbapenems are still effective against gram-negative bacilli causing BSIs, except for <i>A. baumannii</i>. More attention should be given to <i>A. baumannii</i>, considering its high resistance against different classes of antimicrobials.
