Febrile Antigen

Titration of patient’s antibodies by agglutination of known bacteria suspensions is valuable in the evaluation of certain diseases. By using known bacteria suspensions with known concentrations, we can use the agglutination reaction that will occur with the patient’s antibodies to evaluate their antibody level. Antibodies produced as a response to a febrile infection can be detected in a similar fashion. The term “febrile” is associated with several organisms that produce a fever in the host. 

Many antibodies are formed when humans fight disease. Among these antibodies are the agglutinins, which are combined with the agglutinogen (homologous antigen) to cause agglutination. Agglutination forms visible clumps of bacteria.  

The Febrile Antigen suspensions are suitable for both the rapid slide and tube agglutination tests, which both detect agglutinins. Febrile Antigen suspensions are killed bacteria, stained to enhance the reading of the test. The somatic ‘O’ antigens are stained blue while the flagellar ‘H’ antigens are stained red.
