Introduction of Shigella Serotyping Shigella Serotyping helps to differentiate serotypes of Shigella. Serotypes refer to separate groups within a species of microorganisms that all share a similar property. More specifically, each serotype has the same number of antigens on its surfaces. For example, Shigella flexneri serotype 1, 2, 2a, S. sonnei, and S. …
Salmonella Serotyping Serotyping is a type of epidemiological marker. It works on the principle of agglutination. agglutination or clumping: Positive No agglutination or clumping: Negative On this basis, Salmonella can differentiate whether Salmonella enterica serotype Typhi or Paratyphi and so on. Serotype O antigen Salmonella enterica serotype Typhi ( …
