[Development of immunoreagents for the diagnostics of intestinal yersiniosis by antigen-binding lymphocytes]
To diagnose intestinal yersiniosis, the detection of antigen-binding lymphocytes (ABL) with respect to Y. enterocolitica O3, O5 and O9 is proposed. Experiments on the immunization of rabbits with Y. enterocolitica LPS of these serovars revealed that immunoreagents, according to the data of cross antigen-dependent rosette formation and its inhibition, had species specificity (ABL of rabbits immunized with Y. enterocolitica did not interact with Salmonella, Shigella and Y. pseudotuberculosis antigens) and serovar specificity. Cross reactions in the detection of ABL by means of specific Y. enterocolitica O9 and Brucella melitensis immunoreagents in rabbits immunized with Y. enterocolitica were absent during the first days and could be detected only of day 25 after the injection of the immunogen. The method for the detection of ABL with the use of newly developed reagents could be used in clinics for the diagnostics of intestinal yersiniosis.

01:10Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

01:33Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
