MeSH headings : Animals; Bacterial Proteins / biosynthesis; Bacterial Proteins / genetics; Bacterial Proteins / metabolism; Chromatin Immunoprecipitation; DNA, Bacterial / metabolism; DNA-Binding Proteins / biosynthesis; DNA-Binding Proteins / metabolism; Disease Models, Animal; Gene Expression Regulation, Bacterial; Gene Knockout Techniques; Genes, Bacterial; Genomic Islands; Mice; Mice, Inbred C3H; Operon; Protein Binding; Repressor Proteins / genetics; Repressor Proteins / metabolism; Salmonella Infections, Animal / microbiology; Salmonella typhimurium / pathogenicity; Salmonella typhimurium / physiology; Survival Analysis; Trans-Activators / biosynthesis; Transcription Factors / biosynthesis; Virulence; Virulence Factors / biosynthesis
topics (OpenAlex): Salmonella and Campylobacter epidemiology; Bacteriophages and microbial interactions; Bacterial Genetics and Biotechnology
TL;DR: Fur is required for virulence in Salmonella enterica serovar Typhimurium and that Fur is necessary for the activation of hilA, as well as of other HilA-dependent genes, invF and sipC, and chromatin immunoprecipitation was used to show that Fur bound to the upstream region of hns in a metal-dependent fashion.
