Incidence of aerobactin production in Gram-negative hospital isolates [PDF]

FEMS Microbiology Letters, 1987
The production of aerobactin was studied in 943 clinical isolates of 14 different Gram-negative genera. Aerobactin-producing strains were isolated in all the genera of Enterobacteriaceae tested, whereas no aerobactin-producing strains were found in the non-enterobacterial genera (Aeromonas, Pseudomonas, Acinetobacter).

Aerobactin production as a virulence factor: A reevaluation

European Journal of Clinical Microbiology & Infectious Diseases, 1988
Iron starvation is one of the major barriers that virulent bacteria must overcome in order to proliferate in the host. Virtually all microorganisms possess high affinity iron (III) transport systems mediated by low molecular weight iron specific chelators called siderophores, the synthesis of which is activated under iron-limiting conditions ...

Aerobactin production by enterotoxigenic Escherichia coli of porcine intestine

Veterinary Microbiology, 1995
Of 135 strains of Escherichia coli from the intestines of healthy and diseased piglets screened, 16 (12%) were positive in a bioassay for aerobactin production. Of these, 15 also carried genetic determinants for heat stable or heat labile enterotoxins.

Biotest zum Nachweis von Hydroxamat‐Fe‐Chelatoren (Aerobactin)

Journal of Basic Microbiology, 1985
AbstractDifferent Salmonella strains were tested for aerobactin production in a hydroxamate‐bioassay with the aerobactin indicator strain E. coli LG 1522. The majority of hospital strains of Salmonella typhimurium produce hydroxamate siderophore. On the other hand S. typhimurium strains belonging to phage type n. c. 1/72/n.

Photoreactivity of Iron(III)−Aerobactin:  Photoproduct Structure and Iron(III) Coordination

Inorganic Chemistry, 2006
UV photolysis of the ferric aerobactin complex results in decarboxylation of the alpha-hydroxy carboxylic acid group of the central citrate moiety of aerobactin. The structure determination of the photooxidized ligand shows that decarboxylation occurs at the citrate moiety forming a 3-ketoglutarate moiety.

Aerobactin production by a planktonic marine Vibrio sp

Limnology and Oceanography, 1993
Production of siderophores by marine bacteria could potentially contribute to metal complexation by organic compounds in seawater. Direct isolation of planktonic marine bacteria on siderophore indicator plates showed that siderophore producers are present.

Aerobactin production of serotyped Escherichia coli from urinary tract infections

Medical Microbiology and Immunology, 1987
Aerobactin production was examined by a bioassay in 467 Escherichia coli urinary strains from girls. All strains were of known O:K:H serotype. 139, 119 and 112 strains were isolates from pyelonephritis (Py), cystitis (Cy) and asymptomatic bacteriuria (ABU), respectively, and 97 were from fecal samples of healthy girls (FN).

Influence of monosaccharides on aerobactin production byAerobacter aerogenes 62-1

Current Microbiology, 1987
Supplementation of cultures ofAerobacter aerogenes 62-1, 43/4 h after initiation of growth withd-glucose (20 mM), resulted in a threefold increase in the production of aerobactin. Administration ofl-lysine under similar conditions led to a twofold incrasse in the yield of the siderophore.

The Plasmid-Specified Aerobactin Iron Uptake System of Escherichia Coli

1985
Escherichia coli is a major aerobic commensal bacterial species in the intestinal flora of a healthy individual. Some strains, however, are pathogenic for man, causing disease by a variety of mechanisms, and with a severity that ranges from the temporary, if acute, discomfort of “turista” to the chronic human tragedy of widespread infant mortality in ...
