Production of aerobactin by some species of the genus Yersinia [PDF]

Journal of Bacteriology, 1986
Seventy-seven isolates of Yersinia species were examined for evidence of hydroxamate biosynthesis. A total of 7 of 12 Y. frederiksenii, 1 of 5 Y. kristensenii, and 5 of 5 Y. intermedia isolates synthesized an hydroxamate species which was chromatographically and electrophoretically identical to aerobactin. Proof that this material was indeed aerobactin

The aerobactin-mediated iron uptake system in Escherichia coli K-12.

, 1991
Some strains of E. coli secrete a low molecular weight compound, aerobactin, with a high affinity for ferric iron. After complexing ferric iron aerobactin may be transported back into the cell and used as a source of iron.

Aerobactin genes in clinical isolates of Escherichia coli [PDF]

Journal of Bacteriology, 1985
The location of the aerobactin gene complex on either the chromosome or plasmid was determined in eight aerobactin-positive clinical isolates of Escherichia coli by Southern hybridization analysis, using as probes the cloned aerobactin genes from the ColV-K30 plasmid.

Characteristics of Hypervirulent Klebsiella pneumoniae: Does Low Expression of rmpA Contribute to the Absence of Hypervirulence?

Frontiers in Microbiology, 2020
Multidrug-resistant hypervirulent Klebsiella pneumoniae (MDR-hvKP) has been increasingly reported and is now recognized as a significant threat to public health; however, characterization of MDR-hvKP has not been systematically investigated.

Biochemical genetics of aerobactin biosynthesis in Escherichia coli [PDF]

FEMS Microbiology Letters, 1986
Single-gene mutants of Escherichia coli defective in aerobactin biosynthesis were incubated under non-growing conditions for 2 h with radiolabelled lysine. Analysis of the intermediates produced suggested that acetylation of lysine may be the first step in aerobactin production.

Subcloning of the cloacin DF13/aerobactin receptor protein and identification of a pColV-K30-determined polypeptide involved in ferric-aerobactin uptake [PDF]

Journal of Bacteriology, 1983
A plasmid containing a pColV-K30 fragment that encoded only for the cloacin DF13/aerobactin receptor protein was constructed. Escherichia coli cells harboring this plasmid were sensitive to cloacin DF13 but were unable to take up ferric-aerobactin. Another pColV-K30-determined polypeptide (molecular weight, 50,000), localized in the membrane fraction ...

Activity and specificity of a mouse monoclonal antibody to ferric aerobactin [PDF]

Infection and Immunity, 1992
We isolated a monoclonal antibody directed against the ferric complex of aerobactin purified from Escherichia coli KH576. This antibody, which we designated MAb AERO1, was identified as an immunoglobulin G, subtype 2. A competitive enzyme-linked immunosorbent assay with MAb AERO1 had a limit of 10 nM for the detection of purified ferric aerobactin and ...

ShiF acts as an auxiliary factor of aerobactin secretion in meningitis Escherichia coli strain S88

BMC Microbiology, 2019
Background The neonatal meningitis E. coli (NMEC) strain S88 carries a ColV plasmid named pS88 which is involved in meningeal virulence. Transcriptional analysis of pS88 in human serum revealed a strong upregulation of an ORF of unknown function: shiF ...

Genomic insights into virulence factors affecting tissue-invasive Klebsiella pneumoniae infection

Annals of Clinical Microbiology and Antimicrobials, 2022
Background The key virulence factors responsible for hypervirulent Klebsiella pneumoniae (hvKp) infection remains elusive. Methods We analyzed K. pneumoniae isolates collected between 2017 and 2019 and defined hvKp as a pyogenic infection.

Aerobactin synthesis genes iucA and iucC contribute to the pathogenicity of avian pathogenic Escherichia coli O2 strain E058. [PDF]

PLoS ONE, 2013
Aerobactin genes are known to be present in virulent strains and absent from avirulent strains, but contributions of iucC and iucA, which are involved in aerobactin synthesis, to the pathogenicity of avian pathogenic Escherichia coli (APEC) have not been
