Abstract

Host inflammation alters the availability of nutrients such as iron to limit microbial growth. However, Salmonella enterica serovar Typhimurium thrives in the inflamed gut by scavenging for iron with siderophores. By administering Escherichia coli strain Nissle 1917, which assimilates iron by similar mechanisms, we show that this nonpathogenic bacterium can outcompete and reduce S. Typhimurium colonization in mouse models of acute colitis and chronic persistent infection. This probiotic activity depends on E. coli Nissle iron acquisition, given that mutants deficient in iron uptake colonize the intestine but do not reduce S. Typhimurium colonization. Additionally, the ability of E. coli Nissle to overcome iron restriction by the host protein lipocalin 2, which counteracts some siderophores, is essential, given that S. Typhimurium is unaffected by E. coli Nissle in lipocalin 2-deficient mice. Thus, iron availability impacts S. Typhimurium growth, and E. coli Nissle reduces S. Typhimurium intestinal colonization by competing for this limiting nutrient.

  • By binding enterobactin, NGAL maintains the balance between commensal bacteria and immune cells in the gut where colitogenic bacteria can reside and secrete high amounts of enterobactin into the intestinal lumen.

    “In doing so, NGAL maintains the balance between commensal bacteria and immune cells in the gut where colitogenic bacteria can reside and secrete high amounts of enterobactin into the intestinal lumen (Deriu et al., 2013;Moschen et al., 2016;Toyonaga et al., 2016).”

    From Iron in infection and immunity (2020) · cites this paper as Deriu et al., 2013

    The Introduction (page unavailable) says lipocalin-2 sequesters iron-bound enterochelin (enterobactin), and the Results describe how this affects commensal E. coli and Salmonella in the inflamed gut. The paper does not establish that NGAL thereby maintains a balance between commensal bacteria and immune cells, or that colitogenic bacteria secrete high amounts of enterobactin into the intestinal lumen.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
