A cluster of carbapenemase-producing Enterobacter cloacae complex ST171 at a tertiary care center demonstrating an ongoing regional threat.

•We observed 5 inpatients with carbapenemase-producing Enterobacter cloacae complex.•Pulsed-field gel electrophoresis patterns for 2 patient isolates were identical.•These 2 patients were in the same intensive care unit room 13 days apart.•Whole genome sequencing showed that these 2 isolates were closely related.•All isolates matched the clonal lineage of the main circulating strain in the region.
