title: Combined cell culture enzyme-linked immunosorbent assay for quantification of poliovirus neutralization- relevant antibodies.
abstract: A combined cell culture enzyme-linked immunosorbent assay (CCC-ELISA) was developed for measuring the neutralizing antipoliovirus antibodies in human sera. The binding of different concentrations of each of the three poliovirus types to BGM cells in the presence and absence of a constant dilution from each test and reference serum was measured in the CCC-ELISA. The titers of the viruses neutralized by each serum were measured with the titration curves and used for interpretation of neutralizing titers to the three poliovirus types. Analysis of human sera revealed that the sensitivity and specificity of the CCC-ELISA and the microneutralization assay were comparable. The CCC-ELISA is nonsubjective, rapid, and highly reproducible. Furthermore, the CCC-ELISA could potentially be used as a seroepidemiologic tool for assessment of the humoral response to the cell culture infectious viruses.
