Role of Catecholate Siderophores in Gram-Negative Bacterial Colonization of the Mouse Gut Open
We investigated the importance of the production of catecholate siderophores, and the utilization of their iron (III) complexes, to colonization of the mouse intestinal tract by Escherichia coli. First, a ΔtonB strain was completely unable…

The Streptomycin-Treated Mouse Intestine Selects <i>Escherichia coli envZ</i> Missense Mutants That Interact with Dense and Diverse Intestinal Microbiota Open
Previously, we reported that the streptomycin-treated mouse intestine selected nonmotile Escherichia coli MG1655 flhDC deletion mutants of E. coli MG1655 with improved colonizing ability that grow 15% faster in vitro in mouse cecal mucus a…

Aerobic respiration and ecology of Escherichia coli in the mouse cecum Open
The gastrointestinal tract contains a complex microbial ecosystem that exists in a symbiotic relationship with its host and plays an important role in maintaining human health. Escherichia coli, a facultative anaerobe, is a commensal bacte…
