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

BackgroundCitrobacter portucalensis is an emerging multidrug-resistant (MDR) pathogen within the Citrobacter genus. Although individual occurrences of blaKPC–2 or blaNDM–1 have been sporadically reported, the coexistence of both carbapenemase genes in a single strain remains extremely rare.MethodsWe...
