Aerobactin-mediated iron uptake by Escherichia coli isolates from human extraintestinal infections [PDF]

Infection and Immunity, 1986
A total of 516 strains of Escherichia coli were screened for the presence and expression of the aerobactin iron uptake system. The incidence was markedly higher among clinical isolates from patients with septicemia (68.8%), pyelonephritis (74.6%), and symptomatic (59.8%) and asymptomatic (63.2%) lower urinary tract infections than among normal human ...

Unravelling the Pathotype, Biofilm, Virulome and Resistome Profile of MultiDrug‐Resistant Bacteria Isolated From Cattle Faeces Using Whole Genome Sequence Analysis

International Journal of Microbiology, Volume 2026, Issue 1, 2026.
The high mortality and morbidity resulting from diarrhoeal cases worldwide are associated with the increasing incidence of antimicrobial resistance (AMR) and represent a serious public health concern. Cattle are a major reservoir of AMR organisms, and faecal shedding may facilitate their transmission into the food chain.

Uropathogenic Escherichia coli (UPEC) strains may carry virulence properties of diarrhoeagenic E-coli [PDF]

, 2008
To analyze whether Escherichia coli strains that cause urinary tract infections (UPEC) share virulence characteristics with the diarrheagenic E. coli (DEC) pathotypes and to recognize their genetic diversity, 225 UPEC strains were examined for the ...

Molecular Mechanisms of Plant Growth–Promoting Rhizobacteria (PGPR) in Biofertilization and Disease Suppression of Crops

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Plant growth–promoting rhizobacteria (PGPR) are beneficial soil bacteria that colonize the rhizosphere and enhance plant growth through direct and indirect mechanisms, including nutrient solubilization, phytohormone production, suppression of phytopathogens, and activation of plant defense mechanisms.

Characterization of an emergent clone of enteroinvasive Escherichia coli circulating in Europe [PDF]

, 2016
Enteroinvasive Escherichia coli (EIEC) cause intestinal illness indistinguishable from that caused by Shigella, mainly in developing countries. Recently an upsurge of cases of EIEC infections has been observed in Europe, with two large outbreaks ...

Analysis of the aerobactin and ferric hydroxamate uptake systems of Yersinia pestis [PDF]

Microbiology, 2007
Yersinia pestis genomes contain genes homologous to the aerobactin receptor (iutA) and biosynthetic genes (iucABCD) as well as the ferric hydroxamate uptake system (fhuCDB) of Escherichia coli. However, iucA is disrupted by a frameshift mutation. An E. coli strain carrying the cloned Y.

Evolutionary Origins and Virulence Determinants of ST25 Hypervirulent Klebsiella pneumoniae in Swine: Genomic Insights and Functional Validation

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
The global spread of multidrug‐resistant hypervirulent Klebsiella pneumoniae (MDR‐HvKp), among which carbapenem‐resistant strains are of major concern, poses a severe threat to public health due to its high mortality rate and extremely limited treatment options.
