Pyogenic liver abscess caused by hypermucoviscous Klebsiella pneumoniae

Community-acquired primary pyogenic liver abscess (PLA) caused by Klebsiella pneumoniae is an emerging infectious entity, with cases reported in the scientific literature over the past 15 y mainly from Taiwan and Asia, but also from Europe and North America. We describe a case of PLA caused by the hypermucoviscous, K1 capsular serotype of Klebsiella pneumoniae in a Canadian man and highlight the unique features of this increasingly common cause of liver abscess.
