Salmonella typhi is a type of Salmonellabacteria. It causes the disease typhoid fever. The organism can be transmitted by the fecal-oral route -- it is excreted by humans in feces and may be transmitted by contaminated water, food, or by person to person contact (with inadequate attention to personal hygiene). In the developed world, Salmonella are readily removed/inactivated by drinking water treatment and by wastewater treatment.
