Hypermucoviscous Klebsiella pneumoniae: A Hypervirulent Strain Masquerading as Metastasis

Cureus, 2023
Hypermucoviscous Klebsiella pneumoniae (HvKP) is a hypervirulent strain of Klebsiella that causes metastatic spread and life-threatening infection. While it is more common among people of Asian descent, it has been increasingly reported globally among people of other ethnicities as well.

Multiple detection of hypermucoviscous and hypervirulent strains of Klebsiella pneumoniae: An emergent health care threat

, 2022
This study focused on the characterization of 19 hypermucoviscous Klebsiella pneumoniae strains, that were identified from 26 hypermucosal strains. In order to identify hypermucoviscous strains of K. pneumoniae, the string test was applied.

Respiratory Commensal Bacteria Increase Protection against Hypermucoviscous Carbapenem-Resistant Klebsiella pneumoniae ST25 Infection

, 2022
In a previous work, we demonstrated that nasally administered Corynebacterium pseudodiphtheriticum 090104 beneficially modulated the respiratory innate immune response and improved the protection against Respiratory Syncytial Virus and Streptococcus ...

A case of Klebsiella pneumoniae hypervirulent phenotype causing necrotizing fasciitis of chest wall: A mono-microbial entity emerging in the Indian subcontinent

Journal of Family Medicine and Primary Care, 2022
Necrotizing fasciitis of the chest wall or upper torso is a rare clinical entity. Monomicrobial Klebsiella pneumoniae as a causative agent of necrotizing fasciitis is far less common than the polymicrobial etiology.

The Small Protein RmpD Drives Hypermucoviscosity in Klebsiella pneumoniae

mBio, 2020
Klebsiella pneumoniae has a remarkable ability to cause a wide range of human diseases. It is divided into two broad classes: classical strains that are a notable problem in health care settings due to multidrug resistance, and hypervirulent (hv) strains
