Genomic characterization of a multidrug-resistant Citrobacter portucalensis isolate co-harboring blaKPC–2 and blaNDM–1 on distinct plasmids

We report a rare clinical <i>C. portucalensis</i> isolate co-harboring two carbapenemase genes on genetically distinct plasmids with divergent mobility. This highlights the species' potential role as a resistance gene reservoir and the need for enhanced molecular surveillance in both clinical and environmental settings.
