This bacterium is causes food poisoning. It can grow on poultry, uncooked eggs, and various meats. When these foods are eaten by humans, Salmonella grows in the intestine, producing such symptoms as headaches, chills, vomiting and diarrhea. The long whiplike hairs projecting from this strain are called "flagella". The flagella move this bacterium. A closely related species of S. thyphimurium is S. typhi, the cause of typhoid fever.
