Salmonella and other species within the family Enterobactericeae have some type of antigen that is :
- O antigen (somatic)
Consisting of lipopolysaccharide containing glucosamine and present in gram-negative bacterial cell wall. The letter 'O' used comes from the word "ohne haunch" in German language means no film. These antigens are generally not heat resistant, except on some strains. This determines the type of antigen serotype of Salmonella, which has about 65 somatic antigens which are numbered 1 through 65.
2. H antigen (flagella)
Is a protein called flagellin and is not heat resistant. Letter H derives from the German language "haunch" which means the film, which is a feature of the growth of bacteria that have flagella. H antigens can be divided into two specific antigen (phase 1) as initially suspected only found in certain somatic group, and non-specific antigen (phase 2).
3. K Antigen (Capsule)
Derived from the German language "Kapsel" or capsule. These antigens found on the outer surface of bacteria, consisting of polysaccharides, and are not heat resistant. In cells that are still alive, perhaps to cover the K antigen O antigen which is heat resistant, so that the resulting cells were unable to perform agglutination reactions with anti Serum O.
4. Vi antigen (virulent)
Several lines of Salmonella, eg S. thypi, containing a capsule which is virulent antigens expressed in the letter Vi. Vi antigen in Samonella affect the virulence of Salmonella.
