Salmonella genus (spp.)
Salmonella is a rod-shaped, Gram-negative, nonspore-forming, motile bacterium that belongs to the Enterobacteriaceae family and the Salmonellae tribe.
- Pullorum and S. Gallinarum are non-motile variants. There are two species of Salmonella that can make people sick: S. enterica and S. typhimurium.
Bongori, S.
Based on the Kaufmann-White typing scheme, which was initially published in 1934, and distinguishes Salmonella strains by their surface and flagellar antigenic characteristics, Salmonella is further split into serotypes. Serotype designations are frequently used to identify Salmonella species.
Salmonella enterica subsp. enterica, for instance, is further broken down into a number of serotypes, including S. Enteritidis and S. Typhimurium, which are prevalent in the United States. (Note that serotype names are not emphasised but species names are.)
There were 44 serotypes known when Kaufmann first put forth the scheme. There were 2,579 different serotypes known as of 2007.
