Compared to classical Klebsiella pneumoniae, hypervirulent Klebsiella pneumoniae (hvKP) exhibits stronger pathogenicity and a greater ability to evade host immune responses. Infections caused by hvKP typically manifest as more severe diseases with higher mortality rates, thereby increasing the complexity and challenges of clinical treatment. The emergence of carbapenem-resistant hvKP (CR-hvKP) exacerbates this predicament. Although there is still confusion regarding the clinical definition and detection standards for hvKP, this article systematically explains the clinical infection characteristics, identification methods, and mechanisms behind the emergence of CR-hvKP. This can enhance clinical staff’s vigilance towards hvKP infections and offer comprehensive and detailed considerations for the diagnosis and treatment of such strains.
