[Standardization of an inhibition ELISA technique for the serologic diagnosis of coxsackie virus group B infections].

An inhibition ELISA technic to detect antibodies aimed at Coxsackie B viruses was standardized. The method was type-specific since it could detect antibodies to 4 Coxsackie B serotypes (it wasn't tried on serotypes B2 and B4 because the strains were not available). The comparison with the neutralization technic showed 85% coincidence, 91% sensitivity and 82% specificity. All the reactives used in the assay were produced in our laboratory.
