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.
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.
If it can be harmful, it can be referred to as pathogen.
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.
A monovalent antigen is a type of antigen that contains only one type of epitope, which is the specific molecular structure that can be recognized by the immune system. This means that the antigen can only trigger a response from one type of antibody.
Yes. It would be rare, however. In this case, the father has the antigen for either type A or B blood. The antigen is not however connected to the H antigen (this is the part that makes him express the O type). If it were connected to the H, he would be either A or B. Therefore, it is possible that his child could receive his antigen and the opposite from the mother in order to be AB type.
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
blood type
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.
It helps to separate blood types
If it can be harmful, it can be referred to as pathogen.
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.
Antigens.
Abwehrstoff or Antigen
the antigen must bind to the receptor
The O antigen is not an antigen that may be found on the surface of an erythrocyte. A and B antigens are present in the ABO blood group system, while the Rh antigen is part of the Rh blood group system. O blood type individuals lack A and B antigens on their red blood cells.
