Currently, there are more than 2500 different serotypes of Salmonella that have been identified, with each having the potential to cause illness in human.

The serotypes Typhimurium have the potential to infect and cause disease in a variety of hosts such as humans, poultry eggs, pigs, rodents and cattle and thus jump the species barrier with ease.

The full nomenclature for Salmonella typhimurium is Salmonella enterica subspecies enteritica serovar typhimurium.

Salmonella typhimurium is most commonly a food borne pathogen, although there have been a few cases of outbreaks caused by contaminated water sources in the United States.

This strains from food animals are passed to the human population via insufficiently cooked meat, eggs and milk.

Infections also can happened when animals are moved or held before slaughter. Salmonella enter the human food chain on raw meat brought into the kitchen and lead to human infection if the meat is cooked only superficially or contaminates other food.

It causes enterocolitis, resulting in diarrheal illness.
