Liver Abscess Caused by Infection with Community-Acquired Klebsiella quasipneumoniae subsp. quasipneumoniae

Emerg Infect Dis. 2016 Mar;22(3):529-31. doi: 10.3201/eid2203.151466.

Abstract

We report a case of pyogenic liver abscess caused by community-acquired Klebsiella quasipneumoniae subsp. quasipneumoniae. The infecting isolate had 2 prominent features of hypervirulent K. pneumoniae strains: the capsular polysaccharide synthesis region for K1 serotype and the integrative and conjugative element ICEKp1, which encodes the virulence factors yersiniabactin, salmochelin, and RmpA.

Keywords: Klebsiella quasipneumoniae subsp. quasipneumoniae; bacteria; capsular serotype K1; integrative and conjugative element ICEKp1; liver abscess.
