Deciphering the relative importance of genetic elements in hypervirulent Klebsiella pneumoniae to guide countermeasure developmentResearch in context

EBioMedicine
Summary: Background: Quantitating the contribution of phenotype-responsible elements in hypervirulent Klebsiella pneumoniae is needed. Methods: Isogenic mutants of four hypervirulent clinical isolates that produced K1 (ST23), K2 (ST86), K20 (ST1544), or

Complete genome and comparative genomic analysis of cefpodoxime resistant Pantoea septica strain GABEPS69 isolated from saliva of a patient diagnosed with treatment resistant schizophrenia

International Journal of Medical Microbiology
Objectives: This study aims to generate the first complete genome of Pantoea septica and provide a thorough genomic characterisation of this under-documented species. The study seeks to enhance understanding of P. septica, clarifying features relevant to

Photodissolution of lepidocrocite (γ-FeOOH) in the presence of desferrioxamine B and aerobactin

, 2009
Batch adsorption and dissolution experiments with lepidocrocite (γ-FeOOH) and two siderophores, desferrioxamine B (DFOB) and aerobactin, were performed between pH 3 and 8 in the dark and under irradiation with UV-visible light.

Cross-border spread of a mosaic resistance (OXA-48) and virulence (aerobactin) plasmid in Klebsiella pneumoniae: a European Antimicrobial Resistance Genes Surveillance Network investigation, Europe, February 2019 to October 2024

Eurosurveillance
An investigation of the European Antimicrobial Resistance Genes Surveillance Network (EURGen-Net) detected the same mosaic IncHI1B(pNDM-MAR) resistance (OXA-48) and virulence (aerobactin) plasmid in 492 Klebsiella pneumoniae isolates from eight European ...

Genotyping of Virulence Factors of Uropathogenic Escherichia coli by PCR

Novelty in Biomedicine, 2015
Background: Escherichia coli is the most causative agent of urinary tract infections (UTIs). Apart from all human infectious diseases, UTI have a high prevalence and in most cases, Escherichia coli is a dominance bacterium which can cause pyelonephritis ...
