Identification of Antimicrobial Resistance Patterns, Type VI Secretion System, and Virulence Factors in Clinical Isolates of Klebsiella pneumoniae: A Cross‐Sectional Study

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Background:Klebsiella pneumoniae is an opportunistic pathogen linked to a range of severe infections. It is classified into classic K. pneumoniae (cKp) and hypervirulent K. pneumoniae (hvKp) forms, with hvKp showing enhanced virulence. This study examines Type VI secretion system (T6SS) presence and virulence factors in cKp and hvKp strains while ...

Carbapenem Resistance Conferred by OXA-48 in K2-ST86 Hypervirulent Klebsiella pneumoniae, France

Emerging Infectious Diseases, 2020
We recovered 2 carbapenem-resistant K2-ST86 hypermucoviscous Klebsiella pneumoniae isolates from patients in France. The isolates had genetic attributes of hypervirulent K. pneumoniae but differed in ability to cause mouse lethality.

Hypermucoviscous polymyxin-resistant Klebsiella pneumoniae from Kolkata, India: Genomic and phenotypic analysis

Journal of Global Antimicrobial Resistance, 2019
Here we report the draft genome sequence of a colistin-resistant hypermucoviscous Klebsiella pneumoniae isolated from a hospitalised patient with acute kidney injury in Kolkata, India.Whole genomic DNA was sequenced using an Illumina HiSeq platform. The generated reads were de novo assembled using SPAdes v.3.7.1.

Detection of Hypervirulence Genes and Drug Resistance in Klebsiella pneumoniae in Diagnostic Microbiology

Scientifica, Volume 2025, Issue 1, 2025.
Objective: Hypervirulent Klebsiella pneumoniae (hvKp) is emerging and gaining notoriety due to the acquisition of drug resistance. Differentiation of hvKp from classical Klebsiella pneumoniae (cKp) is essential for prompt initiation of therapy to prevent metastasis, detection of occult abscesses, and site‐specific management for better patient outcomes.

Genomic Diversity and Coexistence of Multidrug‐Resistance Mechanisms of Klebsiella pneumoniae in Poultry Farms

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Klebsiella pneumoniae is an opportunistic pathogen and poses a serious threat to the livestock industry and human health. Therefore, it is necessary to investigate the prevalence of K. pneumoniae in agricultural settings. In this study, fecal and environmental samples from poultry farms were collected, and the antibiotic resistance prevalence and ...

Hypermucoviscous Klebsiella syndrome it's in the community!

JPMA. The Journal of the Pakistan Medical Association, 2019
Hypermucoviscous Klebsiella syndrome is a unique syndrome caused by a new variant of Klebsiella pneumoniae (KP), characterized by abscess formation at distant body sites. This emerging KP strain is different from the usual classic strains in having the rmp gene which increases capsule formation making this strain resistant to phagocytosis and helping ...
