Abstract

Klebsiella pneumoniae (Kp) has emerged as an important cause of two distinct public health threats: multi-drug resistant (MDR) healthcare-associated infections and community-acquired invasive infections, particularly pyogenic liver abscess. The majority of MDR hospital outbreaks are caused by a subset of Kp clones with a high prevalence of acquired antimicrobial resistance (AMR) genes, while the majority of community-acquired invasive infections are caused by hypervirulent clones that rarely harbour acquired AMR genes but have high prevalence of key virulence loci. Worryingly, the last few years have seen increasing reports of convergence of MDR and the key virulence genes within individual ..
