Evidence for clonal dissemination of the serotype K1 Klebsiella pneumoniae strain causing invasive liver abscesses in Korea

Abstract

Seventy-three liver abscess isolates of serotype K1 Klebsiella pneumoniae from a nationwide collection in Korea were genotypically characterized using pulsed-field gel electrophoresis and multilocus sequence typing. We found that serotype K1 K. pneumoniae strains that caused liver abscesses in Korea were genotypically related and that most were sequence type 23.
