Salmonella enterica enterica

Salmonella enterica enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella. Many of the pathogenic serovars of the S. enterica species are in this subspecies.

Serovars (not an all-inclusive list, as there are >2,500)

 * Salmonella Choleraesuis
 * Salmonella Dublin
 * Salmonella Enteritidis
 * Salmonella Gallinarum
 * Salmonella Hadar
 * Salmonella Heidelberg
 * Salmonella Infantis

Nomenclature
The serovars can be designated fully or in a shortened form. The short form lists the genus, Salmonella, which is followed by the capitalized and non-italicized serovar. The full designation for Salmonella Typhi is Salmonella enterica enterica, serovar Typhi. Each serovar can have many strains as well, which allows for a rapid increase in the total number of antigenically variable bacteria.
