Most of the iron in a mammalian body is complexed with various proteins. Moreover, in
response to infection, iron availability is reduced in both extracellular and intracellular …

The low concentration of free iron in body fluids creates bacteriostatic conditions for many
microorganisms and is therefore an important defense factor of the body against invading …

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 …

The neurotransmitter norepinephrine (NE) stimulates the growth of low inocula of
Escherichia coli in a minimal medium (SAPI) supplemented with serum (SAPI+ serum) and …

Iron is now recognized as playing a vital role in infection. Not only does its restricted
availability in tissue fluids present microbial pathogens with the problem of acquiring …

Iron is an essential element for most living organisms. Its roles in microbial physiology are
numerous. Iron is a constituent of all haem enzymes, which include cytochromes and …

In Gram-negative bacteria an iron-deficient state is required for both induction of desferri-
siderophores and overproduction of the cognate outer membrane receptor proteins. Thus …

Host–microbe interactions often begin with colonization of mucosal surfaces. These
relationships are highly specific, as certain microbial species are found only in particular …

Ferric enterobactin utilization by Bordetella bronchiseptica and Bordetella pertussis requires
the BfeA outer membrane receptor. Under iron-depleted growth conditions, transcription of …

One common feature amongst the many complex interactions which occur between host and
pathogen during infection, is the ability of the invading organism to multiply in host tissues …
