Enterobacter Species: Opportunistic Human and Plant Pathogens With Plant‐Beneficial Traits

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
The pathogen profile on Enterobacter species synthesises current knowledge on host range, disease symptoms, plant‐beneficial traits and compares genomic features within the genus. ABSTRACT Enterobacter species occur across diverse habitats and are best known for causing opportunistic and nosocomial infections in humans.

The Siderophore Synthetase IucA of the Aerobactin Biosynthetic Pathway Uses an Ordered Mechanism

Biochemistry, 2020
Biosynthesis of the hydroxamate siderophore aerobactin requires the activity of four proteins encoded within the iuc operon. Recently, we biochemically reconstituted the biosynthetic pathway and structurally characterized IucA and IucC, two enzymes that sequentially couple N6-acetyl-N6-hydroxylysine to the primary carboxylates of citrate. IucA and IucC

Isolation, identification, and pathogenic potential of Bacillus cereus from diseased big‐belly seahorse Hippocampus abdominalis

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Members of Bacillus cereus have been documented as important bacterial pathogens in aquaculture. However, scarce information is available on B. cereus isolates as causal pathogens of big‐belly seahorses Hippocampus abdominalis. In the present study, a B. cereus isolate (SH1), recovered from a disease outbreak on a seahorse farm, was identified

Photoreactivity of Iron(III)−Aerobactin:  Photoproduct Structure and Iron(III) Coordination

, 2016
UV photolysis of the ferric aerobactin complex results in decarboxylation of the α-hydroxy carboxylic acid group of the central citrate moiety of aerobactin. The structure determination of the photooxidized ligand shows that decarboxylation occurs at the

Interplay Between Phenotype and Genotype in Multidrug‐Resistant and Hypervirulent Klebsiella pneumoniae Isolates From Southern Bangladesh

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2026, Issue 1, 2026.
Klebsiella pneumoniae (Kpn) is an opportunistic bacterium associated with various diseases, with significant morbidity and mortality due to treatment challenges posed by hypervirulent and multidrug‐resistant (MDR) strains. This study investigates the prevalence of antimicrobial resistance, virulence factors, and clonal diversity of Kpn isolates.

Frequency evaluation of genes encoding siderophores and the effects of different concentrations of Fe ions on growth rate of uropathogenic Escherichia coli

Iranian Journal of Microbiology, 2017
Background and Objectives: Bacteria need iron for growth and most of them can actively acquire Fe ions using especial iron-chelating proteins which named siderophores.

Prevalence and Molecular Characterization of Carbapenemase and Hypervirulence Genes in Klebsiella pneumoniae Isolates in Hospitals of Benghazi, Libya

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Klebsiella pneumoniae is a leading cause of hospital‐acquired infections, particularly in intensive care units (ICUs), where multidrug‐resistant (MDR) and hypervirulent strains represent major therapeutic challenges. This study investigated the phenotypic and molecular features of isolates recovered from ICU patients and the hospital environment in ...

Co‐Occurrence of Resistance to Aminoglycosides and Carbapenems in Klebsiella pneumoniae: A Critical Threat to Public Health

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
Antimicrobial resistance (AMR) in Klebsiella pneumoniae, especially the co‐occurrence of resistance to aminoglycosides and carbapenems, represents a serious threat to global public health. This study reviews the prevalence of this combined resistance, analyzes the underlying mechanisms, and evaluates its impact on clinical practice and public health ...

Virulence Factors and Antibiotic Resistance of Klebsiella pneumoniae Strains Isolated From Neonates With Sepsis

Frontiers in Medicine, 2018
Introduction:Klebsiella pneumoniae is one of the most important infectious agents in neonates. There are “classic” and hypervirulent strains of K. pneumoniae. The “classic” non-virulent strain of K. pneumoniae, producing extended-spectrum beta-lactamases
