Fur regulon in gram-negative bacteria. Identification and characterization of new iron-regulated Escherichia coli genes by a fur titration assay.
TLDR
The Fur titration assay (FURTA) enabled identification of cloned iron-regulated genes from different Gram-positive and Gram-negative bacteria such as: Bacillus subtilis, Escherichia coli, Pantoea agglomerans, Pseudomonas putida, Salmonella typhimurium, Serratia marcescens and Yersinia enterocolitica.

Gut inflammation provides a respiratory electron acceptor for Salmonella
TLDR
It is shown that reactive oxygen species generated during inflammation react with endogenous, luminal sulphur compounds (thiosulphate) to form a new respiratory electron acceptor, tetrathionate, that allows the pathogen to use respiration to compete with fermenting gut microbes.

Evolution of the Chaperone/Usher Assembly Pathway: Fimbrial Classification Goes Greek
TLDR
The phylogeny of operons belonging to the chaperone/usher assembly class is reviewed to explore the utility of establishing a scheme for subdividing them into clades of phylogenetically related gene clusters.

Phase and Antigenic Variation in Bacteria
TLDR
This review provides an overview of the many bacterial proteins and structures that are under the control of phase or antigenic variation, and the way in which these mechanisms form part of the general regulatory network of the cell is addressed.

Molecular Pathogenesis of Salmonella enterica Serotype Typhimurium-Induced Diarrhea
TLDR
Improved understanding of key events occurring during the complex series of host-pathogen interactions leading to enterocolitis is led to an improved understanding of the molecular pathogenesis.

Salmonella typhimurium leucine‐rich repeat proteins are targeted to the SPI1 and SPI2 type III secretion systems
TLDR
Two Salmonella typhimurium genes, sspH1 and sSpH2, that encode proteins similar to the Shigella flexneri and Yersinia species TTSS substrates, IpaH and YopM, were identified and deleted, indicating that these genes participate in S. typhIMurium virulence for animals.

Extraintestinal dissemination of Salmonella by CD18-expressing phagocytes
TLDR
It is reported that Salmonella is transported from the gastrointestinal tract to the bloodstream by CD18-expressing phagocytes, and thatCD18-deficient mice are resistant to dissemination ofSalmonella to the liver and spleen after oral administration.

Microbiota-activated PPAR-γ signaling inhibits dysbiotic Enterobacteriaceae expansion
TLDR
Microbiota-activated PPAR-γ signaling is a homeostatic pathway that prevents a dysbiotic expansion of potentially pathogenic Escherichia and Salmonella by reducing the bioavailability of respiratory electron acceptors to Enterobacteriaceae in the lumen of the colon.

Ethanolamine utilization in Salmonella typhimurium: nucleotide sequence, protein expression, and mutational analysis of the cchA cchB eutE eutJ eutG eutH gene cluster
TLDR
The deduced amino acid sequences of the EutE and EutG proteins revealed a significant degree of homology with the Escherichia coli alcohol dehydrogenase AdhE sequence, indicating that ethanolamine may be an important source of nitrogen and carbon for S. typhimurium in vivo.
