Citrobacter rodentium is an Unstable Pathogen Showing Evidence of Significant Genomic Flux

Citrobacter rodentium is a natural mouse pathogen that causes attaching and effacing (A/E) lesions. It shares a common virulence strategy with the clinically significant human A/E pathogens enteropathogenic E. coli (EPEC) and enterohaemorrhagic E. coli (EHEC) and is widely used to model this route of pathogenesis. We previously reported the complete genome sequence of C. rodentium ICC168, where...

Quorum sensing has an unexpected role in virulence in the model pathogen Citrobacter rodentium.

The bacterial mouse pathogen Citrobacter rodentium causes attaching and effacing (AE) lesions in the same manner as pathogenic Escherichia coli, and is an important model for this mode of pathogenesis. Quorum sensing (QS) involves chemical signalling by bacteria to regulate gene expression in response to cell density. E. coli has never been reported to have N-acylhomoserine lactone (AHL) QS, bu...

Citrobacter rodentium Subverts ATP Flux and Cholesterol Homeostasis in Intestinal Epithelial Cells In Vivo

The intestinal epithelial cells (IECs) that line the gut form a robust line of defense against ingested pathogens. We investigated the impact of infection with the enteric pathogen Citrobacter rodentium on mouse IEC metabolism using global proteomic and targeted metabolomics and lipidomics. The major signatures of the infection were upregulation of the sugar transporter Sglt4, aerobic glycolysi...

Role of RpoS in the virulence of Citrobacter rodentium.

Citrobacter rodentium is a mouse enteropathogen that is closely related to Escherichia coli and causes severe colonic hyperplasia and bloody diarrhea. C. rodentium infection requires expression of genes of the locus of enterocyte effacement (LEE) pathogenicity island, which simulates infection by enteropathogenic E. coli and enterohemorrhagic E. coli in the human intestine, providing an effecti...

Genetic and biochemical characterization of Citrobacter rodentium sp. nov.

An unusual bacterial pathogen of laboratory mice has been previously classified as an atypical biotype of Citrobacter freundii. Designated C. freundii biotype 4280, this bacterium is the etiologic agent of transmissible murine clonic hyperplasia. An eaeA gene has been shown to be present in this organism and to be necessary for virulence in laboratory mice. However, other biotypes of C. freundi...
