Article Title: Detection of carbapenemases in Enterobacterales susceptible in vitro to meropenem.
Article Snippet: Introduction: Carbapenemase-producing Enterobacterales (CPE) is a global threat.. We evaluate the prevalence of CPE among isolates categorized as meropenem-susceptible, but that meet the European Committee on Antimicrobial Susceptibility Testing (EUCAST) screening cut-off values for carbapenemase detection, and analyze the susceptibility of these isolates to new available drugs.. Methods: We analyzed 257 isolates from patients hospitalized in a tertiary hospital in Brazil, from July 2022 to April 2023.
