We report on a carbapenemase-producing hypervirulent Klebsiella pneumoniae (CP-hvKP) isolate collected from a U.S. patient at an outpatient clinic. The isolate was identified as K. pneumoniae serotype K1 sequence type 23 and included both a hypervirulence (with rmpA, rmpA2 iroBCDN, peg-344, and iucABCD-iutA genes) and a carbapenemase-encoding (blaKPC-2) plasmid. The emergence of CP-hvKP underscores the importance of clinical awareness of this pathotype and the need for continued monitoring of CP-hvKP in the United States.
Keywords: Klebsiella; hypervirulence; plasmid-mediated resistance.
