[Sero-diagnosis for human parvovirus B19 infection by IgM and IgG antibody capture method of enzyme-linked immunosorbent assay--study on an epidemic case of erythema infectiosum].
The IgM and IgG antibody capture methods of the enzyme-linked immunosorbent assay (ELISA) for human parvovirus B19 were performed using Horseradish peroxidase (HRPO)-labeled anti B19 monoclonal antibody. Serially obtained serum samples from one erythema infectiosum (E.I.) patient were examined at once by this methods. The dOD values of the IgM and IgG antibodies decreased on the typical curves according to the course of recovery. In the epidemic case of E.I. among students of one nurse school, 1) The first patients was estimated by comparing the change of dOD values of sera obtained at end of the epidemic and 1.5 months later. 2) In the pre-existing antibody positive persons, the dOD values of IgG antibody did not changed during the epidemic. 3) After the E.I. epidemic, and approximately 30% of the students were remained uninfected.
