In this study, we identified the iron‐transport systems of Escherichia coli O157: H7 strain
EDL933. This strain synthesized and transported enterobactin and had a ferric citrate …

Shigella species can use heme as the sole source of iron. In this work, the heme utilization
locus of Shigella dysenteriae was cloned and characterized. A cosmid bank of S …

The uropathogenic Escherichia coli strain CFT073 has multiple iron acquisition systems,
including heme and siderophore transporters. A tonB mutant derivative of CFT073 failed to …

The ability to transport and use haemin as an iron source is frequently observed in clinical
isolates of Shigella spp. and pathogenic Escherichia coli. We found that many of these haem …

Vibrio cholerae was found to have two sets of genes encoding TonB, ExbB and ExbD
proteins. The first set (tonB1, exbB1, exbD1) was obtained by complementation of a V …

Serratia marcescens W225 expresses an unconventional iron (III) transport system. Uptake
of Fe3+ occurs in the absence of an iron (III)-solubilizing siderophore, of an outer membrane …

The study of iron uptake promoted by 2, 3-dihydroxybenzoate (DHB) into Escherichia coli K-
12 aroB mutants allowed some dissection of outer and cytoplasmic membrane functions …

When a strain (arcB-) of Escherichia coli, unable to synthesize the iron transport compound
enterochelin, was transduced to tonB-, it became resistant to phage phi80 and …

The nucleotide sequence of the Escherichia coli fep genomic region has been determined.
Three new loci were identified. One of these, P43, encodes a membrane protein that is not …

Shigella dysenteriae serotype 1, a major cause of bacillary dysentery in humans, can use
heme as a source of iron. Genes for the transport of heme into the bacterial cell have been …
