Clinical implications of hypermucoviscosity phenotype in Klebsiella pneumoniae isolates: association with invasive syndrome in patients with community‐acquired bacteraemia [PDF]

Journal of Internal Medicine, 2006
Abstract.Background.  Klebsiella pneumoniae, a Gram‐negative bacillus usually forming glistening mucoid colonies with viscid consistency on the culture plate, is a common pathogen causing various clinical infection patterns. However, little is known about the clinical implications of this mucoid character.Objective.

A Simple Scoring Algorithm That Predicts Abscesses in Adults with Community-Onset Klebsiella pneumoniae Bacteremia: Hypermucoviscosity Matters.

Infection and drug resistance, 2020
Klebsiella pneumoniae is a pathogen commonly found in community-onset bacteremia. It causes an invasive syndrome that is frequently presented by metastatic infections and abscesses elsewhere and that is necessary for surgical or drainage intervention. To achieve a scoring algorithm to identify patients with community-onset K.

Evolutionary Origins and Virulence Determinants of ST25 Hypervirulent Klebsiella pneumoniae in Swine: Genomic Insights and Functional Validation

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
The global spread of multidrug‐resistant hypervirulent Klebsiella pneumoniae (MDR‐HvKp), among which carbapenem‐resistant strains are of major concern, poses a severe threat to public health due to its high mortality rate and extremely limited treatment options.

Assessment of Hypervirulent Klebsiella pneumoniae Isolates Using Multilocus Sequence Typing in West of Iran

MicrobiologyOpen, Volume 14, Issue 4, August 2025.
This study identified eight novel sequence types (STs) of hypervirulent Klebsiella pneumoniae using MLST in western Iran. The findings highlight the genetic diversity and public health threat posed by hvKP strains. Phenotypic and genotypic methods, including PCR and MLST, were used to identify hypervirulent Klebsiella pneumoniae isolates in western ...
