Poliovirus-Binding Inhibition ELISA for Evaluation of Immune Response to Oral Poliovirus Vaccine: A Possible Alternative to the Neutralization Test.

Ivanov AP, Dragunsky EM, Ivanova OE, Rezapkin GV, Potapova SG, Chumakov KM


This study describes an ELISA variant (Binding Inhibition ELISA, BI ELISA) for the quantitative determination of neutralization-relevant antibodies to polioviruses. The test differs from previously described analogs by utilizing polyclonal immune reagents: capture antibodies and biotin-labeled detecting antibodies. The BI ELISA was compared with the conventional neutralization test (NT) by testing live Sabin and wild-type poliovirus strains. The comparison of 68 serum samples taken from Oral Poliovirus Vaccine (OPV) recipients showed 100% specificity and sensitivity for Sabin 1 and Sabin 2, and 100% sensitivity and 97% specificity for Sabin 3. Good correlations (r = 0.7, 0.77, 0.65 for Sabin 1, 2, 3, respectively) were demonstrated between the NT and BI ELISA results. These results indicate that the BI ELISA can be used as a reliable alternative to the NT for determination of neutralization-relevant antibodies to polioviruses in vaccinees and in large-scale sero-epidemiological studies.
