All types of salmonella come from the genus Salmonella, the bacteria then gets divided up into categories. The majority of the components in each bacteria are about 95% identical for example E. coli and Salmonella are around 60% identical at the DNA level.

There are 3 main serovars of salmonella; Typhimurium, Typhi and Enteritidis. A serovar is a distinct variation of a bacteria and are classed together based upon their similarities. The distinct types help the scientists create effective treatment to target the certain type of salmonella, which makes the treatment more effective because it distinguishes the exact strain of salmonella to cure it.
