Klebsiella pneumoniae, first described in 1882, remains a common cause of community-acquired and hospital-acquired infections; but strikingly, the past three decades have witnessed the emergence of two largely non-overlapping K pneumoniae populations: one multidrug resistant (MDR) and one hypervirulent. These strains belong primarily to a few major clonal groups (CGs), such as the K pneumoniae carbapenemase (KPC)-producing CG258 strains, which cause about 50% mortality in high-risk patients admitted to hospitals; and CG23 strains, which are associated with community-acquired pyogenic liver abscess.
