ABSTRACT: Background
Emergence of blaKPC and blaNDM co-harboring Klebsiella pneumoniae has escalated the threat of Carbapenem-resistant Klebsiella pneumoniae (CRKP) to healthcare. It remains unknown the prevalence and molecular characteristics of CRKP co-producing KPC and NDMs carbapenemases in Henan.Methods and results
Twenty-seven CRKP strains isolated from different times were selected randomly in affiliated cancer hospital of Zhengzhou University from January 2019 to January 2021, among which one KPC-2 and NDM-5 positive CRKP named K9 was isolated from an abdominal pus sample of a 63-year-old male patient with leukemia. Sequencing of K9 determined that K9 belonged to ST11-KL47, which is resistant to antibiotics such as meropenem, ceftazidime-avibactam and tetracycline. K9 carried two different plasmids that contained blaNDM-5 and blaKPC-2. Both plasmids were shown to be novel hybrid plasmids and IS26 played an important role in generation of two plasmids. Gene blaKPC-2 was flanked by the NTEKPC-Ib-like genetic structure (IS26-ΔTn3-ISKpn8-blaKPC-2-ISKpn6-IS26) and was located on a conjugative IncFII/R/N type hybrid plasmid.Conclusion
The resistance gene blaNDM-5 located on a region organized as IS26-blaNDM-5-ble-trpF-dsbD-ISCR1-sul1-aadA2-dfrA12-IntI1-IS26 was carried by a phage-plasmid. We described a clinical CRKP co-producing KPC-2 and NDM-5 and emphasized an urgent need to control their further spread.
