1. An antibody that causes clumping or agglutination of the bacteria or other cells that either stimulated the formation of the a., or contain immunologically similar, reactive antigen. SYN: agglutinating antibody, immune a.. 2. A substance, other than a specific agglutinating antibody, that causes organic particles to agglutinate, e.g., plant a..

- blood group agglutinins see Blood Groups appendix.

- chief a. SYN: major a..

- cold a. an antibody which reacts more efficiently at temperatures below 37°C.

- cross-reacting a. SYN: group a..

- flagellar a. SYN: H a. (1).

- group a. an immune a. specific for a “shared” or common antigen. SYN: cross-reacting a..

- H a. 1. an a. that is formed as the result of stimulation by, and which reacts with, the thermolabile antigen(s) in the flagella of motile strains of microorganisms; SYN: flagellar a.. 2. see ABO blood group, Blood Groups appendix.

- immune a. SYN: a. (1).

- incomplete a. (a-gloo′ti-nin) antibody that binds to antigen but does not induce agglutination. These antibodies are usually of the IgG class and are referred to as incomplete antibody.

- major a. immune a. present in greatest quantity in an antiserum and evoked by the most dominant of a mosaic of antigens. SYN: chief a..

- minor a. immune a. present in an antiserum in lesser concentration than the major a.. SYN: partial a..

- O a. 1. an a. that is formed as the result of stimulation by, and that reacts with, the relatively thermostable antigen(s) that are part of the cell wall of certain microorganisms; SYN: somatic a.. 2. see ABO blood group, Blood Groups appendix.

- partial a. SYN: minor a..

- plant a. a lectin.

- saline a. an antibody that causes agglutination of erythrocytes when they are suspended either in saline or in a protein medium. SYN: complete antibody.

- somatic a. SYN: O a. (1).

- warm agglutinins an a. that is more reactive at 37°C than at lower temperatures.
