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 ...

Microbiological and Clinical Characteristics of Hypermucoviscous Klebsiella pneumoniae Isolates Associated with Invasive Infections in China

Frontiers in Cellular and Infection Microbiology, 2017
A distinctive syndrome caused by hypermucoviscous Klebsiella pneumoniae (HMKP) including pyogenic liver abscess (PLA) is now becoming a globally emerging disease. In the present study, 22.8% (84/369) of K. pneumoniae clinical isolates associated with various types of invasive infections were identified as HMKP, with 45.2% associated with PLA ...

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.

Comparative genetic analysis of the antimicrobial susceptibilities and virulence of hypermucoviscous and non-hypermucoviscous ESBL-producing Klebsiella pneumoniae in Japan

, 2022
Background Hypermucoviscous (HMV) Klebsiella pneumoniae produces large amounts of capsular polysaccharides, leading to high mortality. Since extended spectrum beta-lactamase (ESBL)-producing HMV K.

Septic arthritis subsequent to urosepsis caused by hypermucoviscous Klebsiella pneumoniae.

Internal medicine (Tokyo, Japan), 2013
We herein report the first case of septic arthritis caused by rmpA-positive hypermucoviscous community-acquired K. pneumoniae that followed urosepsis in a 65-year-old Japanese woman. The patient responded well to drainage of the abscesses and treatment with cefazolin. Although this virulent phenotype of K. pneumoniae has been primarily reported in Hong

Identification and Characterization of NDM-1-producing Hypervirulent (Hypermucoviscous) Klebsiella pneumoniae in China

Annals of Laboratory Medicine, 2019
Carbapenem-resistant hypervirulent (hypermucoviscous) Klebsiella pneumoniae (CR-HMKP) poses a significant public health challenge. We investigated its epidemiology and molecular characteristics in a tertiary care hospital in eastern China.CR-HMKP were identified among 106 non-duplicated carbapenem-resistant K.
