Eleks Test

1950 – L. J. Elek introduced the in vitro precipitation test for determining toxin production by C. diphtheriae. This became known as Elek’s test.

Elek’s test is based on immunodiffusion:

Diphtheria toxin + diphtheria antitoxin → visible precipitin line

A strip of filter paper containing diphtheria antitoxin is placed on an agar plate. The suspected C. diphtheriae strains are streaked perpendicular to the strip.

Herbert Durham Reaction

                                           

The Gruber–Durham reaction refers to the bacterial agglutination reaction discovered independently by Max von Gruber and Herbert Edward Durham in 1896.

• Max von Gruber (Austrian bacteriologist) and Herbert Edward Durham (British bacteriologist) demonstrated that the serum of an animal immunized against a particular bacterium could cause visible clumping (agglutination) of that bacterium.
• Their work provided one of the earliest demonstrations of a specific antigen–antibody reaction.
• The reaction became an important basis for serological diagnosis and bacterial identification.
