We investigated sinks as possible sources of a prolonged KPC-producing K. oxytoca outbreak. Seven carbapenem resistant K. oxytoca isolates were identified in sink drains in 4 patient rooms and in the medication room. Investigations for resistance genes and genetic relatedness of patient and environmental isolates revealed that all isolates harboured the blaKPC-2 and blaTEM-1 and were genetically indistinguishable. We describe a clonal outbreak caused by KPC-2-producing K. oxytoca pointing to handwashing sinks as possible reservoir.
