  3. Apr 10, 2024 · Agglutination reaction is an antigen-antibody reaction that leads to the visible clumping of particles. It occurs when a particulate antigen combines with its corresponding antibody in the presence of electrolytes, at a specific temperature and pH.

    A ring precipitation test is used for grouping streptococci and for determining unknown proteins.

    Single-diffusion assays, which are also called immunodiffusion assays, can be used to determine the concentration of immunoglobulins, complement components, and other serum proteins.

    This test is used to diagnose several fungal, viral and bacterial infections. In addi-tion, it can be used to diagnose autoimmune diseases and to recognize Corynebacterium diphtheriae-produced toxins.

    The agglutination test is used widely, for example, in detecting streptococci group B toxins, rheumatoid arthritis, and C-reactive proteins.

    Blood grouping, virus identification and in the detection of certain diseases.

    In the ring precipitation test, antigen interaction with antibodies occurs at: The top layer of the reaction tube. (b) The middle layer of the reaction tube. The bottom layer of the reaction tube. (d) None of the above. 2. Gel diffusion can be: Single. (b) Double. (c) Ring. (d) a and b. In the direct agglutination test: Pathogen and patient antibod...

  4. When multiple antibodies bind to multiple antigens on diferent pathogens, it leads to agglutination. This clumping makes it easier for immune cells to engulf and eliminate the pathogens, thus enhancing the body's defense against infection. In microbiology, agglutination can occur in various ways.

  7. Agglutination can be used as an indicator of the presence of antibodies against bacteria or red blood cells. Agglutination assays are usually quick and easy to perform on a glass slide or microtitre plate (Figure 21.15).
