Description
The serological typing of one stipe of Salmonella occurs through two successive stages that lead to the definition of the serogroup and serotype. The first step consists in the determination of the specificity of somatic O. The second step consists in the determination of the specificity flagellum H, monophasic or biphasic.
MONOPHASIC: the flagella of bacteria have the same specificity. (ex. S. Typhi 9,12 (Vi): d)
BIPHASIC: the bacteria can alternatively express 2 different specificities; ( ex. S. Paratyphi B 1, 4, 5, 12 ,: b: 1,2)
Some serotypes, such as S. Typhi and S. Dublin can present the capsular antigen Vi (virulence factor) that may not allow the agglutination with the sera binders of Salmonella anti-O.
