In vivo bioluminescence imaging of Escherichia coli O104:H4 and role of aerobactin during colonization of a mouse model of infection

BMC Microbiology, 2012
Background A major outbreak of bloody diarrhea associated with Shiga toxin-producing Escherichia coli O104:H4 occurred early in 2011, to which an unusual number of hemolytic uremic syndrome cases were linked.

The iucC gene is a major contributor to the virulence of hypervirulent Klebsiella pneumoniae

Frontiers in Cellular and Infection Microbiology
BackgroundHypervirulent Klebsiella pneumoniae (hvKp) is a critical pathogen that causes highly lethal invasive infections with its virulence linked to that of aerobactin, the core siderophore system of hvKp.MethodsHere, 20 porcine-derived K.

Presence and expression of aerobactin genes in virulent avian strains of Escherichia coli [PDF]

Infection and Immunity, 1987
Virulent and nonvirulent isolates of avian Escherichia coli were tested for the presence of aerobactin genes by colony hybridization with a specific gene probe constructed from plasmid pABN1 (A. Bindereif and J. B. Neilands, J. Bacteriol. 153:1111-1113, 1983).

Exploring Cervical Cancer‐Associated Vaginal and Cervical Microbiota via 16S rRNA Sequencing

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
This 16S sequencing study identified a dysbiotic cervical microbiota (increased diversity, reduced Lactobacillus, enriched Prevotella) specifically linked to high‐risk HPV infection. These microbial alterations, shaped by the HPV‐driven microenvironment, offer novel targets for biomarkers and mechanistic research in cervical carcinogenesis.

Flanking and internal regions of chromosomal genes mediating aerobactin iron uptake systems in enteroinvasive Escherichia coli and Shigella flexneri

, 1987
We have investigated the presence of the aerobactin system and the location of the aerobactin genes in enteroinvasive strains of Escherichia coli.

First Report of blaCTX‐M‐15 in a Marine Thermotolerant Enterobacter Isolate From Bangladesh: Genomic Insights Into Halotolerance and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Marine‐derived Enterobacter kobei, exhibiting thermotolerance and salt tolerance, is ESBL‐producing and harbors AMR genes (blaCTX‐M‐15, qnrS1) and mobile genetic elements, indicating environmental spread of antimicrobial resistance. ABSTRACT Marine ecosystems are becoming important reservoirs for antimicrobial resistance (AMR). However, genomic data on

Expression of aerobactin genes by Shigella flexneri during extracellular and intracellular growth [PDF]

Infection and Immunity, 1997
The expression of the Shigella flexneri chromosomal aerobactin genes during growth of the bacterium within tissue culture cells was assayed. During intracellular growth, aerobactin promoter activity was repressed relative to the level observed in bacteria grown extracellularly, even when the bacteria had been starved for iron prior to infection ...

Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

Aerobactin Synthesis Proteins as Antivirulence Targets in Hypervirulent Klebsiella pneumoniae [PDF]

ACS Infectious Diseases, 2019
Hypervirulent Klebsiella pneumoniae (hvKp) is an underrecognized pathotype of K. pneumoniae since the majority of cases have occurred in East Asia. However, hvKp is a public health threat due to its ability to infect healthy individuals, ongoing dissemination, and acquisition of resistance determinants.
