Improvement of transformation efficiency in hypermucoviscous Klebsiella pneumoniae using citric acid.

Journal of Microbiological Methods, 2023
Transformation efficiency is very low in hypermucoviscous Kllebsiella pneumoniae owing to high amount of capsular polysaccharide. Here, we propose a method to improve the transformation in hypermucoviscous K. pneumoniae using citric acid.

Hypermucoviscous Klebsiella Pneumoniae Caused Community-Acquired Pneumonia in Gondar, Northwest Ethiopia.

Clinical Laboratory
BACKGROUND The incidence of hypermucoviscous Klebsiella pneumoniae (hmvKp), which complicates community-acquired pneumonia, has been increasing recently. This study aimed to detect hypermucoviscous K.

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

Journal of Microbiology, Immunology and Infection, 2023
Hypermucoviscous (HMV) Klebsiella pneumoniae produces large amounts of capsular polysaccharides, leading to high mortality. Since extended spectrum beta-lactamase (ESBL)-producing HMV K. pneumoniae strains have increased in Japan, we investigated and compared the antimicrobial susceptibilities and genetic characteristics of HMV and non-HMV ESBL ...

Hypermucoviscous Klebsiella pneumoniae: A challenge in community acquired infection

IDCases, 2019
In 1986, a new syndrome was described in Taiwan secondary to hypervirulent K. pneumoniae (hvKP), and its main feature was the ability to cause severe infection in young and immunocompetent hosts. Their virulence is explained by the efficient acquisition of iron and an increase in capsule production, which confer the characteristic hypermucoviscous ...

Biofilm formation of hypermucoviscous and non-hypermucoviscous Klebsiella pneumoniae recovered from clinically affected African green monkey ( Chlorocebus aethiops sabaeus )

Microbial Pathogenesis, 2017
In recent years, an emergent Klebsiella pneumoniae hypermucoviscous (HMV) phenotype has been associated with increased invasiveness and pathogenicity in primates. The HMV phenotype is characterized by different capsular serotypes, associated with several genes including the rmpA (regulator of mucoid phenotype) and magA (mucoviscosity-associated) genes.

The Detection of Hypermucoviscous Carbapenem-Resistant Klebsiella pneumoniae from a Tertiary Teaching Hospital in Malaysia and Assessment of Hypermucoviscous as Marker of Hypervirulence

Microbial Drug Resistance, 2021
Background: Hypermucoviscous carbapenem-resistant Klebsiella pneumoniae (hmCRKp) is emerging globally and approaching the worst-case scenario in health care system ...

Pyogenic liver abscess caused by hypermucoviscous Klebsiella pneumoniae

Scandinavian Journal of Infectious Diseases, 2007
Community-acquired primary pyogenic liver abscess (PLA) caused by Klebsiella pneumoniae is an emerging infectious entity, with cases reported in the scientific literature over the past 15 y mainly from Taiwan and Asia, but also from Europe and North America.

Fatal pneumocephalus caused by hypermucoviscous hydrogen-producing Klebsiella pneumoniae capsular genotype K63 in a patient with diabetic ketoacidosis

Journal of Microbiology and Infectious Diseases
Background: Klebsiella pneumoniae is associated with respiratory infection, liver abscess, and meningitis, but rarely with pneumocephalus. In recent decades, only eight cases of pneumocephalus caused by K.

Necrotizing fasciitis following psoas muscle abscess caused by hypermucoviscous Klebsiella pneumoniae

Journal of Infection and Chemotherapy, 2012
A 59-year-old Japanese diabetic woman was admitted to a small private hospital with general malaise, fever, and a 1-month history of low back pain. A computed tomography scan of the abdomen revealed left abdominal necrotizing fasciitis with suspected left psoas muscle abscess.
