Some foodborne outbreaks have been linked to enterotoxigenic C. freundii; patients typically exhibit diarrhea. This pathogen may also produce a Shiga-like toxin and produce hemolytic uremic syndrome.
Citrobacter species are differentiated by their ability to convert tryptophan to indole, ferment lactose, and use malonate.
Citrobacter produces sulfur-smelling hydrogen sulfide, which is toxic to mitochondria and may compromise the ability of cells to make energy properly. The resulting symptom you’d be most likely to experience is fatigue.
