Agglutinin A substance that will cause a clumping of particles such as bacteria or erythrocytes. Of major importance are the specific or immune agglutinins, which are antibodies that will agglutinate bacteria containing the corresponding antigens on their surfaces. Agglutinins are readily determined, and their presence is of diagnostic value to indicate present or past host contact with the microbial agent sufficient to result in antibody formation. See Agglutination reaction, Antibody Analogous reactions involve erythrocytes and their corresponding antibodies, the hemagglutinins. Hemagglutinins to a variety of erthyrocytes occur in many normal sera, and their amounts may be increased by immunization. The blood group isoagglutinins of humans and animals are important special cases which must be considered in all proposed blood transfusions lest transfusion reactions result. See Blood groups agglutinin[ə′glüt·ən·ən] (immunology) An antibody from normal or immune serum that causes clumping of its complementary particulate antigen, such as bacteria or erythrocytes. agglutininenUK
agglutinin [ah-gloo´tĭ-nin] any substance causing agglutination" >agglutination (clumping together) of cells, particularly a specific antibody formed in the blood in response to the presence of an invading agent. Agglutinins are proteins (immunoglobulins) and function as part of the immune mechanism of the body. When the invading agents that bring about the production of agglutinins are bacteria, the agglutinins produced bring about agglutination of the bacterial cells.
Erythrocytes also may agglutinate when agglutinins are formed in response to the entrance of noncompatible blood cells into the bloodstream. A transfusion reaction is an example of the result of agglutination of blood cells brought about by agglutinins produced in the recipient's blood in response to incompatible or foreign cells (the donor's blood). Anti-Rh agglutinins are produced in cases of Rh incompatibility and can result in a condition known as erythroblastosis fetalis when the maternal blood is Rh negative and the fetal blood is Rh positive.
