Successful containment of the first KPC-producing Klebsiella pneumoniae outbreak in Croatia.

AIM: We report the first outbreak caused by Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae sequence type 258 (ST 258) clone that occurred in Croatia from May to December 2012.

MATERIALS & METHODS: 23 carbapenem-resistant K. pneumoniae isolates were recovered from clinical and screening specimens of 12 patients hospitalized in a regional hospital. The first isolates from the 12 patients were typed using pulsed-field gel electrophoresis and multilocus sequence typing.

RESULTS: PCR detection showed that all isolates harbored the bla KPC-2 gene, together with bla TEM-116 and bla SHV-11 .

CONCLUSION: The rapid detection of KPC-producing K. pneumoniae and vigorous implementation of infection control measures were necessary to successfully control the outbreak.
