Active surveillance for carbapenem-resistant Acinetobacter baumannii (CRAB) carriage.

IMPORTANCE: Our study's results provide promising evidence for the incorporation of a high-sensitivity carbapenem-resistant Acinetobacter baumannii (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.

Identification and control of two outbreaks of unrelated New Delhi metallo-ß-lactamase-producing carbapenem-resistant Escherichia coli traced to the same endoscope defect.

We report 2 outbreaks of genetically unrelated carbapenem-resistant New Delhi metallo-ß-lactamase-producing Escherichia coli caused by contaminated duodenoscopes. Using endoscopes with disposable end caps, adherence to the manufacturer's reprocessing instructions, routine audits, and manufacturer evaluation are critical in preventing such outbreaks.
