Marker for Widal Test carried out for the detection of Salmonella
You can differentiate between different salmonella strains using serology. Each strain has its own combination of antigens. Depending on the O, H, and vi antigens, you can determine which strain is present. The O-antigen is the somatic polysaccharide antigen, the H-antigen is the flagellar antigen and the vi-antigen is the capsular antigen. Antibodies to most of the variants of these antigens are available commercially for use in labs. Adding an aliquot of specific antisera to a suspension of your salmonella spp, and incubating it for a few hours in a water bath will result in visible agglutination if your salmonella strain possesses the specific antigen to the antibody you added. For example, Salmonella typhi will show agglutination with O [9,12], H [d] and vi.
S Typhi H is an antigen associated with Salmonella Typhi, the bacterium responsible for causing typhoid fever. This antigen is used to detect the presence of antibodies in a person's blood, indicating a past or current infection with Salmonella Typhi.
In a Widal test, "H" refers to the flagella antigen of Salmonella typhi while "O" refers to the somatic antigen of the bacteria. The presence of antibodies against these antigens indicates a recent or current infection with Salmonella typhi, the bacterium that causes typhoid fever.
you might be suffering from typhoid fever as o antigen more than 100 and h antigen more than 200 are significant consult your doctor immediately for proper treatment dr.mahwash
It helps to separate blood types
The H is 1. the antigen in the flagella of motile (moving) bacteria; important in serologic classification of enteric (intestinal) bacteria. 2. the chemical precursor of antigens of the ABO blood group locus. Some are very rare types seen in only a few types. It is called "Oh" and also the Bombay (now the city Mumbai) Group.
Antigens.
The Latin name for Salmonella is Salmonella enterica.
Yes.
Abwehrstoff or Antigen
the antigen must bind to the receptor
No they do not have salmonella in it only if they get contaminated then it is possible for some to have salmonella?
