Virulence and genomic features of a blaCTX-M-3 and blaCTX-M-14 coharboring hypermucoviscous Klebsiella pneumoniae of serotype K2 and ST65

摘要

BackgroundCapsular serotype K2 Klebsiella pneumoniae of sequence type (ST) 65 has been recognized as a hypervirulent clone. Simultaneous presence of different blaCTX-M genes has never been reported in this clone. In the present study, the genetic characteristics and virulence phenotype of a CTX-M-3 and CTX-M-14 coproducing ST65 K. pneumoniae human isolate, KP_06, that caused an intracranial infection, are evaluated.
