Liver abscess caused by infection with community-acquired klebsiella quasipneumoniae subsp. Quasipneumoniae

Abstract

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