Salmonella can also be divided into three groups based on how well the organism is adapted to human hosts:

The genus Salmonella is divided into two species, S. enterica and S. bongori involving> 2,400 known serotypes. Some of these serotypes have names. In such cases, the scientific name is sometimes shortened in common use by only the genus and the serotype be specified; z. B. S. enterica subspecies enterica serotype Typhi is shortened to Salmonella Typhi. Salmonella can also be divided into three groups based on how well the organism is adapted to human hosts: Highly adapted to the human host serotypes and those who have no nonhumanen hosts: to this group include S. Typhi and S. Paratyphi A , B (also called S. schottmuelleri) and C (also called S. Hirschfeldii) that are pathogenic for humans and often cause typhoid. Those that are not adapted to human hosts or almost exclusively in animals cause diseases. Some strains within this group-S. Dublin (cattle), S. arizonae (reptiles) and S. choleraesuis (pigs) -verursachen diseases in humans. Serotypes with a variety of hosts: to this group belong> 2000 serotypes (eg S. Enteritidis, S. Typhimurium.) That can cause gastroenteritis and are responsible for about 85% of all Salmonella infections in the United States.
