Pathogenic Potential of Invasive Mucosa‐Associated Klebsiella pneumoniae Isolates in Ulcerative Colitis: Characterization of Virulence Factors and Inflammatory Response

Immunity, Inflammation and Disease, Volume 13, Issue 10, October 2025.
This study was conducted in 83 patients with ulcerative colitis (UC). Klebsiella pneumoniae isolates showed a higher prevalence of virulence genes (fimH, hcp, fyuA, irp1) compared to non‐UC controls. UC isolates exhibited increased adhesion (29% vs. 8%) and invasion (16% vs.

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.
