H antigens correspond to the antigenic type of the bacterial flagella
O antigens correspond to the antigenic type of the Lipopolysaccharide layer on the outer membrane of gram negative bacteria
bacteria all have different antigenic types on their surface which react to different types of antibodies and are classified using this method. For example the pathogenic E. coli O157:H7 has the designation 157 for its O antigen meaning it will not react with antibodies with a different serotype.

What is difference between S Typhi O and S Typhi H?
There is a great difference between S Typhi O and H. The S Typhi O is somatic, and H is flagella.
Is hoh an element?
No, it is a water molecule H - O - H. It is made of two elements, oxygen (O) and hydrogen (H). It is not linear, but has a bond angle of 104.5 degrees.
Is O blood type universal?
Type O blood is considered to be the universal blood type. This is because it does not have either A or B antigens on the red cells. It does however contain the antibodies for each one in the plasma.
What is a example of molecule?
H(subscript 2)O
MHC antigens are?
Peptides
What blood type has no antigens?
Previous answer: 0 blood type has no antigens.My improved answer: the Bombay phenotype has no antigens.O blood group has H antigens (but does not have A or B antigens), whereas in the Bombay phenotype blood group, even the H antigens are absent.Glenn LowNUS Life Sciences Studentsimmune system
Why is type O considered the "universal donor"?
A type A blood sample contains A antigens which will conflict with any sample that does not have A antigens (B, O). O contains no antigens and therefore is compatible with all blood types.
Do Group O types have Antigens?
Your husband would be incorrect, blood types that have Antigens would be type A and B and AB. Type O means you do not have any Antigens in your blood.
Does anybody know what are the 4 blood types ?
Te four basic blood types are O, A, B and AB. They are named for the types of antigens they carry. O has no antigens, A has A antigens, B has B antigens and AB carries both.
Which antigens are present in your plasma if you have type O blood?
Your blood type is determined by antibodies (both/either A and B), and Antigens present (both/either A and B) in your Red Blood Cells. O blood types have both A and B antibodies, and neither A or B antigens. If you are O+ it means you can give blood to anyone. If you are O- it means you can recieve any blood type.
What are the A B AB and O blood groups distinguished by?
Blood types are distinguished by the type of antigen on the red blood cells. Type A has A antigens, type B has B antigens type AB has both antigens and type O has none.
What types of blood can people who are O positive accept?
People with O blood can only accept O blood. this is because type O blood does not have any antigens. Types A, B, and AB blood have A or B antigens, or both, respectively. If a person receives blood with antigens their blood does not contain it will cause their blood to clot and they will die.
Can mother ab and father o have o babies?
No, they cannot, the child will either have A antigens, B antigens or AB antigens The answer above may be correct, but it is impossible to check all blood types of couples who will get married. (JW70), (Moreover, I think it is not correct.)
What antigens and antibodies are in O- blood type?
there are no antigen in O blood and both A and B antigen in O blood.
How do you identify different Salmonella species by biochemical test?
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.
What blood type of blood has no anitgens?
O... O has no antigens, so it has antibodies for both A and B.
What is a person with neither a nor b antigens in his or her blood?
you would be type O
