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

Phylogeny, Resistome, and Virulome of Escherichia coli Causing Biliary Tract Infections [PDF]
Escherichia coli is the most frequent Gram-negative bacilli involved in intra-abdominal infections. However, despite high mortality rates associated with biliary tract infections due to E. coli, there is no study focusing on this pathogen. In this study,

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

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

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

Aerobactin production and plasmid distribution in Escherichia coli clinical isolates [PDF]
The distribution of plasmids as a function of aerobactin production, antibiotic resistance and antimicrobial agents production was studied in 139 Escherichia coli strains obtained from clinical sources. Ninety eight per cent of the strains analyzed presented plasmids with a median value of 2.97 plasmids per cell.
