Prevalence of multidrug-resistant hypervirulent Klebsiella pneumoniae without defined hypervirulent biomarkers in Anhui, China: a new dimension of hypervirulence

Frontiers in Microbiology, 2023
Klebsiella pneumoniae is an opportunistic pathogen that mainly causes nosocomial infections and hospital-associated pneumonia in elderly and immunocompromised people. However, multidrug-resistant hypervirulent K.

Antimicrobial Resistance, Virulence, and Genomic Characteristics of <i>Klebsiella pneumoniae</i> Isolated From Four Host Sources in Northeast China. [PDF]

Transbound Emerg Dis
Klebsiella pneumoniae is an important emerging pathogen leading to serious clinical outcomes as the multidrug‐resistant (MDR) isolates arise. While K. pneumoniae is a well‐known pathogen in human clinical settings, its risks in nonhuman hosts and potential for cross‐species transmission remain poorly understood. In this study, we performed whole‐genome

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.

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.

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.

Loss of Hypermucoviscosity and Increased Fitness Cost in Colistin-Resistant Klebsiella pneumoniae Sequence Type 23 Strains [PDF]

Antimicrobial Agents and Chemotherapy, 2015
ABSTRACT In this study, we investigated the effects of colistin resistance on virulence and fitness in hypermucoviscous (HV) Klebsiella pneumoniae sequence type 23 (ST23) strains. Colistin-resistant mutants were developed from three colistin-susceptible HV K. pneumoniae ST23 strains.
