Phenotypic and molecular characterization of Klebsiella spp. isolates causing community-acquired infections

New Microbes and New Infections, 2018
Klebsiella spp. isolates from community-acquired infections were characterized. A total of 39 Klebsiella spp. isolates were obtained from outpatients at four rural hospitals in Mexico (2013–2014).

[Liver abscess syndrome with lung involvement secondary to hypermucoviscosity Klebsiella pneumoniae].

Gaceta medica de Mexico, 2013
Klebsiella pneumoniae liver abscess syndrome (KLAS) is an emerging infection characterized by primary monomicrobial liver abscess, bacteremia and metastatic complications. KLAS is endemic in Taiwan but additional cases has also been described in other world regions. It’s caused by strains of K.

Assessment of Biofilm Formation and Hypermucoviscosity in Klebsiella oxytoca from Clinical and Community Sources

Journal of the Faculty of Medicine Baghdad
Background: Klebsiella oxytoca is an emerging pathogen causing hospital- and community-acquired infections. Hypermucoviscous phenotype and biofilm development are considered markers of hypervirulence, causing invasive infections in healthy adultsObjective: The current study aimed to evaluate the ability of K.

Genomic Analysis of Multidrug-Resistant Hypervirulent (Hypermucoviscous) Klebsiella pneumoniae Strain Lacking the Hypermucoviscous Regulators (rmpA/rmpA2)

, 2022
Hypervirulent K. pneumoniae (hvKP) strains possess distinct characteristics such as hypermucoviscosity, unique serotypes, and virulence factors associated with high pathogenicity.

Adaptive attenuation of virulence mediated by Wzc mutation in ST11-KL47 Carbapenem-resistant Klebsiella pneumonia

Frontiers in Cellular and Infection Microbiology
IntroductionThe impact of the hypermucoviscosity (HMV) phenotype in ST11-KL47 carbapenem-resistant Klebsiella pneumoniae (CRKp) pathogenicity warrants investigation for public health risk assessment.MethodsWe analyzed 230 clinical ST11-KL47 CRKp to ...

Insights into the recognition of hypermucoviscous Klebsiella pneumoniae clinical isolates by innate immune lectins of the Siglec and galectin families

Frontiers in Immunology
Klebsiella pneumoniae is an opportunistic bacterium that frequently colonizes the nasopharynx and gastrointestinal tract and can also cause severe infections when invading other tissues, particularly in immunocompromised individuals.

Development of an impedance assay-based model highlighting the crucial role of hypermucoviscosity in hypervirulent K. pneumoniae pathophysiology

Background Hypervirulent Klebsiella pneumoniae (HvKp) cause pyogenic liver abscesses (PLA) in otherwise healthy people. Molecular surveillance of HvKp reveal that the global dissemination of HvKp poses an urgent threat to human health.

Biofilm at the interface air-liquid (ALI-biofilm).

, 2019
A. Representative sample of ALI-biofilm. The positive strain (right tube) forms a thick, while in the negative strain (left tube) no pellicle has been detected. The ring structure attaches to the wall of the tube (central tube). B.

A k2A-positive Klebsiella pneumoniae causes liver and brain abscess in a Saint Kitt's man [PDF]

, 2009
Klebsiella pneumoniae isolated in community-acquired pneumonia is increasingly found in primary pyogenic liver abscesses. The presence of magA in K. pneumoniae has been implicated in hypermucoviscosity and virulence of liver abscess isolates.

Mucoviscosity and resistance to human serum linked to the Hmv-associated genes (magA and/or rmpA).

, 2019
A. Hypermucoviscosity levels were determined as the OD600 of the supernatant obtained after centrifugation of an overnight culture at 1,000×g for 5 minutes. B. Survival of K. pneumoniae strains in 75% NHS compared to 75% HI-NHS.
