Many types of Salmonella bacteria cause salmonellosis in animals and people. While the occurrence of different types of Salmonella varies from country to country, S. typhimurium and S. enteritidis are the two most commonly found in the United States.
Some strains of Salmonella have become resistant to several antibiotics normally used to treat people with salmonella disease, posing a serious public health threat.
