Case Report of an Extensively Drug-Resistant Klebsiella pneumoniae Infection With Genomic Characterization of the Strain and Review of Similar Cases in the United States

: Reports of extensively drug-resistant and pan-drug-resistant Klebsiella pneumoniae (XDR-KP and PDR-KP) cases are increasing worldwide. Here, we report a case of XDR-KP with an in-depth molecular characterization of resistance genes using whole-genome sequencing, and we review all cases of XDR-KP and PDR-KP reported in the United States to date.
