This serovar was first isolated from cattle in Ghana in 1952, since then numerous outbreaks in the U.S. and Europe have occurred. Multi Locus Sequence Typing (MLST) has identified only four sequence types. A Salmonella serotype is determined by the unique combination of reactions of cell surface antigens. The "O" antigen is determined by the outermost portion of the Lipopolysaccharide (LPS) and the "H" antigen is based on the flagellar (protein) antigens. There are two species of Salmonella: Salmonella bongori and Salmonella enterica. Other Salmonella serovars have a broader host range and mainly cause gastroenteritis in animals and humans; they are referred to as nontyphoidal Salmonella (NTS).

There are currently 2,463 serotypes (serovars) of Salmonella. The antigenic formulae of Salmonella serotypes are defined and maintained by the World Health Organization (WHO) Collaborating Centre for Reference and Research on Salmonella at the Pasteur Institute, Paris, France (WHO Collaborating Centre), and new serotypes are listed in annual updates of the Kauffmann-White scheme ( 18 , 19 ). The Salmonella from intestinal contents belong to Salmonella enterica subsp. enterica serovars 45: d: 1, 7 (11) and S .

enterica and S. bongori—there are around 2,500 serovars of the bacterium, each with unique features, behavior and origin. In order to track and trace the source of an outbreak, analysts must therefore identify the serovar involved; this traditionally involves isolation followed by culture using selective media.

The recent completion of the genome sequences of several Salmonella serovars, allied with the application of whole genome analyses, and the availability of Den serotyp som sprids mellan smafaglar och orsakar infektion ar Salmonella Epidemiology of a Salmonella enterica subsp. enterica Serovar Typhimurium In case isolates of Salmonella serovar typhimurium and Salmonella serovar enteritidis are phage typed (optional), the methods described by WHO reference Frekomst av salmonella inom fjderffoderindustrin i Pakistan.
The National Salmonella Reference Laboratory at CDC assists public health laboratories in the United States in serotype identification by providing procedure manuals, training workshops, updates, and assistance with the identification of problem isolates. There are currently 2,463 serotypes (serovars) of Salmonella (18). Data indicate that prevalence of specific serovars of Salmonella enterica in human foodborne illness is not correlated with their prevalence in feed.
