title: Immunodiagnosis of human dirofilariasis by enzyme-linked immunosorbent assay using recombinant DNA-derived fusion protein.
abstract: An enzyme-linked immunosorbent assay (ELISA) using antigenic beta-galactosidase-Dirofilaria immitis recombinant fusion protein (FP) obtained by the recombinant DNA technique provided a useful diagnostic tool for human dirofilariasis. D. immitis-infected human sera reacted strongly with FP that was immobilized with anti-beta-galactosidase monoclonal antibody on microplates. However, the FP did not react with sera from patients with other filariasis. In detection of anti-D. immitis IgG antibody. ELISA using FP was highly sensitive and specific compared to that using crude somatic antigen.
