Typhoid and Paratyphoid (Enteric) Fever enterica includes over 1400 serotypes. Although the full name of the cause of typhoid fever is Salmonella enterica subsp. enterica serotype Typhi, it is normally just shortened to: S. Typhi.
How are Salmonella serotypes named?
Serotype names designated by antigenic formulae include the following: (i) subspecies designation (subspecies I through VI), (ii) O (somatic) antigens followed by a colon, (iii) H (flagellar) antigens (phase 1) followed by a colon, and (iv) H antigens (phase 2, if present) (for example, Salmonella serotype IV 45:g,z51: …
