Klebsiella pneumoniae (K. pneumoniae), an essential opportunistic Gram-negative bacteria and just about the most widespread pathogenic bacteria in hospitals (Ballen et al.Fadrozole Protocol , 2021), is responsible for the frequent incidence of a serious hospitaland community-acquired infections, like urinary tract infections, lung infections, and bloodstream infections (M Campos et al.Sodium molybdate Epigenetics , 2020; Hu et al.PMID:26644518 , 2021). Studies have shown that the clinical detection price of K. pneumoniae is second only to Escherichia coli, exhibiting a year-on-year enhance (Yang F. et al., 2019). In recent years, the resistance of K. pneumoniae to antibacterial drugs has been increasing, as a result, carbapenems, as a result of their broad antibacterial spectrum and sturdy antibacterial activity, are being increasingly employed to treat serious bacterial infections (Doi, 2019). Even so, the wide use and abuse of carbapenems in clinical practice is providing rise to carbapenem-resistant K. pneumoniae (CRKP), even causing nosocomial infection outbreaks, posing considerable challenges to clinical remedy (Candan and Aksoz, 2015; Xu et al., 2017; Tang et al., 2020; Zhao et al., 2020). As outlined by virulence characteristics, K. pneumoniae could be classified as classic K. pneumoniae (cKp) and hypervirulent K. pneumoni.
