Hypervirulent Klebsiella pneumoniae [PDF]

Open Forum Infectious Diseases, 2014
Abstract Hypervirulent strains of Klebsiella pneumoniae are associated with abscess formation, commonly hepatic, and metastatic spread, even in healthy patients. We describe a case of this clinical syndrome, genotypic and phenotypic features of the isolate, and briefly review epidemiology, clinical manifestations, and pathogenesis of ...

Prevalence of multidrug-resistant hypervirulent Klebsiella pneumoniae without defined hypervirulent biomarkers in Anhui, China: a new dimension of hypervirulence

Frontiers in Microbiology, 2023
Klebsiella pneumoniae is an opportunistic pathogen that mainly causes nosocomial infections and hospital-associated pneumonia in elderly and immunocompromised people. However, multidrug-resistant hypervirulent K. pneumoniae (MDR-hvKp) has emerged recently as a serious threat to global health that can infect both immunocompromised and healthy ...

Ruptured Emphysematous Prostatic Abscess Caused by K1-ST23 Hypervirulent Klebsiella pneumoniae Presenting as Brain Abscesses: A Case Report and Literature Review

Frontiers in Medicine, 2022
Emphysematous prostatic abscess (EPA) is an extremely rare but potentially fatal urinary tract infection (UTI). Here, we describe a case (a 69-year-old male with prediabetes) of ruptured EPA caused by a hypervirulent Klebsiella pneumoniae (hvKp) K1-ST23 ...
