    Abstract:
    An enzyme-linked immunosorbent assay for the demonstration of mumps immunoglobulin G (IgG ELISA) and immunoglobulin M antibodies (IgM ELISA) in serum was compared with complement fixation (CF), hemagglutination inhibition (HI), and hemolysis-in-gel (HIG) tests. The antibody levels measured by IgG ELISA had a high positive correlation with the CF and HIG tests, whereas only a moderate correlation was found between IgG ELISA and HI. Similar patterns of antibody response were observed with IgG ELISA, CF, and HIG: the antibody tires increased rapidly after the onset of symptoms and reached the maximal values in about three weeks. The HI antibodies developed more slowly during the first week of disease, after which the titres increased rapidly up to the fourth week. IgM antibodies measured by ELISA developed soon after onset of symptoms; most patients had IgM antibodies from the second day, and the highest titres were reached within the first week. The antibody response in mumps parotitis did not differ from that in mumps meningitis/encephalitis, while relatively higher antibody titres were found in patients with orchitis/epididymitis. The diagnostic efficiencies of the methods were compared with serum specimens from 33 patients who had a serologically verified mumps infection by at least one of the five methods used (rising antibody titres in paired sera or detectable IgM): IgM ELISA detected all 33 cases, IgG ELISA 29, HIG 28, HI 23, and CF 13. In 27 cases, IgM antibodies were already present in the acute phase serum specimens. It was concluded that mumps IgM ELISA is a more rapid and sensitive means for the serological diagnosis of mumps infection than the conventional tests.
