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.
