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.

Impact of Iron Deficiency on the Growth and Bioelectrical Profile of Different Gut Bacteria

MicrobiologyOpen, Volume 14, Issue 3, June 2025.
This study explores how iron deficiency (ID) affects Escherichia coli (E. coli) and Limosilactobacillus reuteri (L. reuteri) under laboratory conditions induced by the iron chelator 2,2'‐Bipyridyl (BP). L. reuteri showed no significant changes, whereas E.

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

Forging the iron‐net: Towards a quantitative understanding of microbial communities via siderophore‐mediated interactions

Quantitative Biology, Volume 13, Issue 2, June 2025.
Abstract Iron is a critical yet limited nutrient for microbial growth. To scavenge iron, most microbes produce siderophores—diverse small molecules with high iron affinities. Different siderophores are specifically recognized and uptaken by corresponding recognizers, enabling targeted interventions and intriguing cheater‐producer dynamics.

Streptomycin-induced inflammation enhances Escherichia coli gut colonization through nitrate respiration. [PDF]

, 2013
UnlabelledTreatment with streptomycin enhances the growth of human commensal Escherichia coli isolates in the mouse intestine, suggesting that the resident microbial community (microbiota) can inhibit the growth of invading microbes, a phenomenon known ...

Molecular Typing of Klebsiella pneumoniae Clinical Isolates by Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction

International Journal of Microbiology, 2020
Aim. Klebsiella pneumoniae is one of the most important causes of nosocomial infections, including pneumonia, sepsis, and urinary tract infection. Enterobacterial repetitive intergenic consensus polymerase chain reaction (ERIC-PCR) technique is a quick ...

Co-cultivation and transcriptome sequencing of two co-existing fish pathogens Moritella viscosa and Aliivibrio wodanis [PDF]

, 2015
Background: Aliivibrio wodanis and Moritella viscosa have often been isolated concurrently from fish with winterulcer disease. Little is known about the interaction between the two bacterial species and how the presence of one bacterial species affects ...
