Hypervirulent (hypermucoviscosity) Klebsiella pneumoniae isolated from clinical samples in Al-Diwaniyah Hospital

International journal of health sciences, 2022
Klebsiella pneumoniae is not only one of the major pathogens acquired from hospital, but it is also one of the pathogens transmitted through urine samples that causes the liver Abscesses, blood poisoning, diarrhea. The study aimed to isolate the Hypervirulent Klebsiella pneumoniae (Hvkp) bacteria from clinical samples in Al-Diwaniyah city / Iraq.

Genomic Epidemiology of Multidrug‐Resistant Clinical Klebsiella pneumoniae From Pakistan

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Study design and bioinformatics workflow. Cohort selection and uniform workflow. ABSTRACT Background Antimicrobial‐resistant Klebsiella pneumoniae is a major clinical threat in Pakistan and the wider South Asian region, where genomic surveillance remains limited. We analyzed 122 publicly available human clinical K.

Hypervirulent Klebsiella pneumoniae Sequence Type 420 with a Chromosomally Inserted Virulence Plasmid [PDF]

, 2021
Background: Klebsiella pneumoniae causes severe diseases including sepsis, pneumonia and wound infections and is differentiated into hypervirulent (hvKp) and classic (cKp) pathotypes.

Adaptation to novel spatially-structured environments is driven by the capsule and alters virulence-associated traits

Nature Communications, 2022
Phenotypic and genotypic evolution in worrisome Klebsiella spp. is influenced by the capsule. Here the authors show that adaptation outside the host can impact virulence-associated traits, including de novo emergence of hypermucoviscosity.

Temperatures above 37°C increase virulence of a convergent Klebsiella pneumoniae sequence type 307 strain

Frontiers in Cellular and Infection Microbiology
BackgroundConvergence of Klebsiella pneumoniae (KP) pathotypes has been increasingly reported in recent years. These pathogens combine features of both multidrug-resistant and hypervirulent KP.

Hypervirulent Klebsiella pneumoniae Infections: A Systematic Review of Clinical, Microbiological, and Outcome Data From Reported Cases

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
Distribution of organ involvement in reported hypervirulent Klebsiella pneumoniae cases. Studies restricted to isolated liver abscess cases were excluded. Percentages represent the proportion of cases with documented involvement of each anatomical site among cases with available data.
