Emergence of a Hypervirulent Tigecycline-Resistant Klebsiella pneumoniae Strain Co-producing bla NDM-1 and bla KPC-2 With an Uncommon Sequence Type ST464 in Southwestern China.


ABSTRACT: Emergence of bla NDM-1 and bla KPC-2 co-producing Klebsiella pneumoniae strains is currently attracting widespread attention, but little information is available about their tigecycline resistance, virulence, and prevalence in Southwest China. In July 2021, an extensively drug-resistant K. pneumoniae strain AHSWKP25 whose genome contained both bla NDM-1 and bla KPC-2 genes was isolated from the blood of a patient with the malignant hematological disease in Luzhou, China. We investigated the resistance profiles of AHSWKP25 using microbroth dilution, agar dilution, modified carbapenemase inactivation (mCIM), and EDTA-modified carbapenemase inactivation methods (eCIM). The virulence of AHSWKP25 was assessed
