Recurrent serotype K1 Klebsiella pneumoniae liver abscess: A single or different pathogen?

Abstract

We report a case of an 81-year-old woman who had a history of type 2 diabetes mellitus with the presentation of a recurrent community-acquired liver abscess caused by capsular serotype K1 〞Klebsiella pneumonia〞 after a previous liver abscess had been cured. With regards to the serotype K1 K. 〞pneumonia〞 strains, the molecular genome of the recurrent strain differed completely from the strain that had caused the primary community-acquired liver abscess even though the antibiogram was the same. This case attempts to highlight that capsular serotype K1 could be an important factor influencing liver abscess formation and its subsequent recurrence.
