Background Carbapenemases produced by Enterobacterales are often encoded by genes on transferable plasmids and represent a major healthcare problem, especially if the plasmids contain additional antibiotic resistance genes. As part of Dutch national surveillance, 50 medical microbiological laboratories submit their Enterobacterales isolates suspected of carbapenemase production to the National Institute for Public Health and the Environment for characterization. All isolates for which carbapenemase production is confirmed are subjected to next-generation sequencing. Objectives To study the molecular characteristics of a genetic cluster of Enterobacter cloacae complex isolates collected in Dutch national surveillance in the period 2015–20 in the Netherlands. Methods Short- and long-read genome sequencing was used in combination with MLST and pan-genome MLST (pgMLST) analyses. Automated antimicrobial susceptibility testing (AST), the Etest for meropenem and the broth microdilution test for colistin were performed. The carbapenem inactivation method was used to assess carbapenemase production. Results pgMLST revealed that nine E. cloacae complex isolates from three different hospitals in the Netherlands differed by Conclusions The EclCluster-013 reported here represents an MDR E. cloacae complex ST78 strain containing an IncH12 plasmid carrying both the blaVIM-1 carbapenemase and the mcr-9 colistin resistance gene.
