The possibility of using different strains of parotitis virus (Enders, L-3, Jeryl-Leen) as antigens for enzyme immunoassay (EIA) to titer antibodies in human and animal blood sera is analyzed. Methods for preparation and purification of antigen on the basis of the said parotitis virus strains have been developed. Conditions of EIA were optimized. The sensitivity and specificity of EIA and hemagglutination inhibition test were compared.
