Ceftazidime-avibactam is a novel combination of a known cephalosporin and a non-β-lactam/β-lactamase inhibitor that has been approved for the treatment of complicated intra-abdominal and urinary tract infections, hospital-acquired pneumonia as well as Gram-negative infections with limited treatment options in Europe. Since its approval, it has been used in patients with infections due to carbapenem-resistant bacteria, in many occasions as off-label indication or salvage therapy, with promising clinical and microbiological cure rates. Emergence of resistance during therapy to this new combination has already been described, which is a matter of concern. A rational use of these new therapeutic options is critical in the multidrug resistance era. The current review focuses on the clinical experience in real life of ceftazidime-avibactam use in the treatment of carbapenemase-producing Enterobacterales.

Unlabelled: Data from low and middle-income countries (LMICs) on multidrug-resistant microorganisms (MDROs) in intensive care units (ICUs) are scarce. Working in several ICUs in Argentina, we sought to estimate the prevalence and characteristics of MDRO infections and carbapenemase-producing Enterobacterales (CPE) colonization. Mortality associated with MDRO infection was also evaluated.

Introduction: The global rise of extended-spectrum beta-lactamase-producing (ESBL-PE) challenges resource-limited countries with insufficient laboratory infrastructure. This study investigates fecal carriage and risk factors for ESBL-PE and carbapenemase-producing organisms among patients with urinary tract infection (UTI) in rural Tanzania.
Methods: This cross-sectional study was conducted at St.

Carbapenemase-producing Enterobacterales are a growing concern in public health. In order to rapidly determine the antimicrobial profile, the MALDI Biotyper - antibiotic susceptibility test rapid assay (MBT-ASTRA) was developed, based on the relative growth of bacteria in the presence of antibiotics. In this study, we added carbapenemase enzymatic inhibitors to the MBT-ASTRA and developed an adapted method named MALDI Biotyper - Phenotypic Identification Test Rapid Assay (MBT-PITRA) in order to perform a rapid and cost-effective phenotypic test to detect Klebsiella pneumoniae carbapenemase (KPC) and New Delhi metallo-beta-lactamase (NDM), including co-producers, in Enterobacterales.

Introduction: Carbapenemase-producing Enterobacterales (CPE) are associated with increased morbidity and mortality in liver transplant recipients (LTRs). There is a paucity of data regarding CPE colonization and infection in Australian LTRs.
Methods: A single-center retrospective cohort study of CPE was performed in LTRs from 2015 to 2024.

Unlabelled: Carbapenem-resistant Enterobacterales (CRE) are divided into two distinct groups: carbapenemase-producing (CPE) and non-carbapenemase-producing (non-CPE). The population of non-CPE growing on CPE selective plates during routine screening is usually not reported and is not well defined. This study aimed to characterize non-CPE isolates growing on those plates.
