    Abstract:
    Enzyme-linked immunosorbent assay (ELISA) systems for serum IgG and IgM antibodies to human parvovirus B19 were established by utilizing anti-B19 monoclonal antibodies (mAbs) and human plasma B19 antigen. The specificities of IgG and IgM ELISA were confirmed by indirect immunofluorescence staining and Western blot immunoassay with panel sera. The series of serum specimens obtained from two B19-infected patients were examined with ELISA. The IgM antibody titers increased quickly after the onset of the symptoms and returned to a negative range after five months. The IgG antibody titers also increased just after the increasing of IgM titers and the elevated levels continued for more than a year. We also established the same ELISA systems by utilizing in vitro propagated B19 antigen and similar results were obtained.
