Phenotypical and molecular assessment of the virulence potential of KPC-3-producing Klebsiella pneumoniae ST392 clinical isolates [PDF]

, 2020
Klebsiella pneumoniae is a Gram-negative bacterium of clinical importance, due to its resistance to several antibiotic classes. We have identified 4 clinical isolates of K.

Microbiological characteristics of hypermucoviscous Klebsiella pneumoniae isolates from different body fluids

The Journal of Infection in Developing Countries, 2017
Introduction: Reports of hypermucoviscous Klebsiella pneumoniae (hvKP) isolated from fluids other than blood or abscess are rare. The aim of the study was to compare clinical and microbiological characteristics of hvKP found in blood or abscess fluid with those isolated from other loci. Methodology: A total of 24 non-repetitive hvKP isolates were

Mechanisms governing bacterial capsular polysaccharide attachment and chain length

Annals of the New York Academy of Sciences, Volume 1548, Issue 1, Page 80-98, June 2025.
Abstract Capsular polysaccharides (CPSs) are high‐molecular weight glycopolymers that form a capsule layer on the surface of many bacterial species. This layer serves as a crucial barrier between bacteria and their environment, protecting them from host immune responses and environmental stressors while facilitating adaptation to host niches.

Rare Hypermucoviscous Klebsiella pneumoniae Liver Abscess in an Active Duty Male Requiring Partial Liver Resection for Definitive Treatment.

Military Medicine, 2023
Antibiotics and drainage have largely replaced hepatic resection for the treatment of liver abscesses in the modern era; however, in cases caused by a rare strain of Klebsiella pneumoniae with a hypermucoviscous phenotype, more aggressive hepatic ...

Increasing Occurrence of Antimicrobial-Resistant Hypervirulent (Hypermucoviscous) Klebsiella pneumoniae Isolates in China [PDF]

Clinical Infectious Diseases, 2013
New hypervirulent variants of Klebsiella pneumoniae (hvKP) are emerging globally, most of which exhibit antimicrobial susceptibility.A retrospective study was conducted in 88 patients with cultures positive for K. pneumoniae hospitalized in the Beijing You'an Hospital from April 2010 to June 2012.

Contribution of disease to Australian sea lion (Neophoca cinerea) pup mortality at Seal Bay, Kangaroo Island, 2016–2022

Marine Mammal Science, Volume 41, Issue 2, April 2025.
Abstract The endangered Australian sea lion (Neophoca cinerea) population is declining, and its conservation is threatened by the species' low fecundity and high pup mortality. This study details reasons for pup deaths and quantifies the impacts of disease and comorbidity. Of 284 dead pups reported from five breeding seasons (2016–2022) at the Seal Bay

Hypermucoviscous capsular 1 (K1) serotype Klebsiella pneumoniae necrotising fasciitis and metastatic endophthalmitis

BMJ Case Reports, 2018
A 48-year-old man presented with a non-healing wound on his left foot after stepping on a nail. He self-medicated with amoxicillin, but the wound progressed prompting consult. On examination, his left foot was diffusely swollen with surrounding erythema, areas of gangrene, foul-smelling purulent discharge and subcutaneous emphysema. He was managed as a

Molecular Epidemiology and Antimicrobial Resistance of Klebsiella pneumoniae Strains Isolated From Dairy Cows in Xinjiang, China

Veterinary Medicine and Science, Volume 11, Issue 1, January 2025.
WGS identified 27 wzi allele types (2 new), 16 K antigen serotypes, 6 O antigen serotypes, 25 sequence types (3 new), 39 antibiotic resistance and 57 virulence genes in Klebsiella pneumoniae from milk samples of cows with and without mastitis. Phylogenetic analysis showed high genomic diversity in K. pneumoniae.

Hypervirulent Klebsiella pneumoniae as Unexpected Cause of Fatal Outbreak in Captive Marmosets, Brazil

Emerging Infectious Diseases, 2020
After the sudden death of captive marmosets in São Paulo, Brazil, we conducted a histologic and microbiologic study. We found hyperacute septicemia caused by hypermucoviscous sequence type 86 K2 Klebsiella pneumoniae.
