Антибиотики и Химиотерапия, 2023 Background. Currently, it is customary to distinguish two pathotypes of Klebsiella pneumoniae — classical and hypervirulent, which have the ability to cause community-acquired infections in healthy people.

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.

Identification and characterisation of novel iron acquisition mechanisms in Sinorhizobium meliloti 2011 and Pseudomonas aeruginosa [PDF]
, 2003 All known microorganisms with the exception of lactobacilli display an absolute requirement for iron. Although iron is the fourth most abundant element on earth, it is rapidly oxidised at neutral pH forming insoluble hydroxides.

Aerobactin production and plasmid distribution in Escherichia coli clinical isolates [PDF]
FEMS Microbiology Letters, 1989 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.

Cloning of the aerobactin-mediated iron assimilation system of plasmid ColV [PDF]
Journal of Bacteriology, 1983 The high-affinity iron assimilation system of plasmid ColV-K30 was cloned on the vector plasmid pPlac. Plasmid pABN1 was isolated by means of sensitivity to cloacin, a bacteriocin using the same outer membrane receptor as ferric aerobactin. Restriction maps were determined for this plasmid and for a subclone, pABN5. Plasmid pABN1 codes for the complete

Structural and functional delineation of aerobactin biosynthesis in hypervirulent Klebsiella pneumoniae [PDF]
Journal of Biological Chemistry, 2018 Aerobactin, a citryl-hydroxamate siderophore, is produced by a number of pathogenic Gram-negative bacteria to aid in iron assimilation. Interest in this well-known siderophore was reignited by recent investigations suggesting that it plays a key role in mediating the enhanced virulence of a hypervirulent pathotype of Klebsiella pneumoniae (hvKP).

Variation in siderophore biosynthetic gene distribution and production across environmental and faecal populations of Escherichia coli. [PDF]
PLoS ONE, 2015 Iron is essential for Escherichia coli growth and survival in the host and the external environment, but its availability is generally low due to the poor solubility of its ferric form in aqueous environments and the presence of iron-withholding proteins

Potential virulence of Klebsiella sp. isolates from enteral diets [PDF]
Brazilian Journal of Medical and Biological Research, 2015 We aimed to evaluate the potential virulence of Klebsiella isolates from enteral diets in hospitals, to support nosocomial infection control measures, especially among critical-care patients.
