Abstract:
A highly sensitive, effective and rapid method--a competitive alternative to ELISA--was developed for the detection of specific antibodies to Y. pseudotuberculosis. It is based on monoclonal antibodies (MAbs) recognizing the species- or serogroup specific epitopes of Y. pseudotuberculosis. The competitive ELISA was used in testing the murine hyperimmune sera and human antisera sampled from patients with different infectious intestinal diseases including several cases of pseudotuberculosis. The use of the MAbs-based ELISA in the laboratory diagnostics of pseudotuberculosis is under discussion.

Enzyme-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.
