Virulence factors are preserved within carbapenem-resistant clades.

Carbapenem-resistant (CRAB) is an important threat to hospitalized patients. The virulence of varies between strains and geographic locations, which is believed to be related to its genetic plasticity. A comprehensive evaluation of virulence factor (VF) content of CRAB across genetically related clones is lacking.

Tailoring Interventions for Control of Endemic Carbapenem-Resistant : An Interrupted Time Series Analysis.

Background: We examined temporal trends in carbapenem-resistant (CRAB) infections in a hospital with hyperendemic CRAB and assessed the efficacy of varied infection control strategies in different ward types.

Methods: We retrospectively analyzed all CRAB clinical samples from 2006 to 2019 and categorized infections as hospital-onset (HO) or community-onset. We used interrupted time series analysis to assess the impact of interventions on the incidence of all HO-CRAB infections and bloodstream infections (BSIs) at the hospital and ward group levels.

Active surveillance for carbapenem-resistant (CRAB) carriage.

Our study's results provide promising evidence for the incorporation of a high-sensitivity carbapenem-resistant (CRAB) screening method in healthcare settings. Such an approach could prove beneficial in enhancing infection prevention and control measures, leading to improved patient outcomes and potentially alleviating the burden of CRAB in healthcare systems.

Occurrence, Typing, and Resistance Genes of ESBL/AmpC-Producing in Fresh Vegetables Purchased in Central Israel.

Beta-lactam resistance can lead to increased mortality, higher healthcare expenses, and limited therapeutic options. The primary mechanism of beta-lactam resistance is the production of extended-spectrum beta-lactamases (ESBL) and AmpC beta-lactamases. The spread of beta-lactamase-producing via the food chain may create a resistance reservoir.

Carbapenem-resistant load in patients and their environment: the importance of detecting carriers.

The environment surrounding 30 of 31 carriers of carbapenem-resistant (CRAB) was contaminated by CRAB. The environmental CRAB loads were similar whether carriers were identified only by surveillance cultures (nonclinical carriers) or also had positive clinical cultures. Screening to detect and isolate nonclinical CRAB carriers may be important to prevent CRAB transmission.
