Over a 5-month period between the end of June and the beginning of November in 2015, a KPC-producing Enterobacteriaceae outbreak occurred in a general hospital in Busan, South Korea, being associated with a total of 50 clinical isolates from 47 patients. Multilocus sequence typing and pulsed-field gel electrophoresis were carried out for strain typing and whole-genome sequencing was performed to characterize the plasmids. A clonal spread of K. pneumoniae sequence type 307 (ST307) carrying a self-transferable IncX3-type plasmid harboring blaKPC-2 was responsible for the outbreak. Sporadic emergence of K. pneumoniae ST697 carrying an IncFII-type plasmid and a ST11 isolate harboring a small plasmid devoid of any known origin of replication were observed to be associated with blaKPC-3, but no further dissemination of these strains was identified. The results indicated a healthcare-associated infection associated with a blaKPC-harboring plasmid dissemination and a clonal spread of KPC-producing Enterobacteriaceae.
