Salmonella Enterica - Nomenclature

Nomenclature

Salmonella enterica has 6 subspecies, and each subspecies has associated serovars that differ by antigenic specificity. There are over 2500 serovars for S. enterica. Salmonella bongori used to be considered a subspecies of S. enterica, but it is now the other species in the Salmonella genus. Most of the human pathogenic Salmonella serovars belong to the S. enterica enterica subspecies. These serogroups include Salmonella Typhi, Salmonella Enteritidis, Salmonella Paratyphi, Salmonella Typhimurium, and Salmonella Choleraesuis. The serovars can be designated as written in the previous sentence (capitalized and non-italicized following the genus), or as follows: "Salmonella enterica enterica, serovar Typhi."
